Linux 2.6 Kernel Stability Freeze

An anonymous reader writes "Linux Creator Linus Torvalds released the 2.6.0-test7 Linux development kernel today and declared a "stability freeze". It has been made quite clear that from this point only "strictly necessary stuff" will be accepted, clearing the way for an official 2.6.0 release sooner than later... possibly at the end of this month."

Time to upgrade!

[caluml]

Great! That means it's really stable now. I shall upgrade the fw at work to this tomorrow. DNS and mailserver as well.

Re:Time to upgrade!

[Short Circuit]

Whoops! Hold on a second.

The stability freeze only means that no new features will be added. There are still lots of bugs to be worked out. Else we'd have a 2.6.0 release instead of a freeze.

Re:Time to upgrade!

[caluml]

Duh! Don't you know anything? Linus 2.6 is the most stable OS ever. A man at the pub told me, and he works in IT selling computers, and I believe him.

Re:Time to upgrade!

[RealAlaskan]

Great! That means it's really stable now.

BZZZZZZZZZT! WRONG! It's a "stability freeze". That means that the stabilizers are frozen, and can't function. So, it will be unstable until they get the stabilizers repaired.

Sheesh. Goofy kids these days...

Aren't you gonna let people whose machines are in less of a production role give it a whirl first?

I hope I'm not in any way a user of your company's machines. I don't like it when people risk their customers' experiences to try out new things. If 2.6.0 becomes are stable as we hope then by all means install it but I would advise a period of scrutiny to determine this first. Even Linus would insist you hang your head in shame for just accepting his offerings at face value.

Just remember: new != better

Sounds to me like it's got a bad motivator

Re:Time to upgrade!

I'm glad Linus drew the line on stability, because we should be working on more important stuff, like new features.

Re:Time to upgrade!

[faccenda]

NOOOOOOOOOOOOOO! It's so stable that is freezing, it can't move anymore.

Re:Time to upgrade!

[q.kontinuum]

That means that the stabilizers are frozen, and can't function.

Bullshit, it means the stability of the kernel is really cool now ;-)

Re:Time to upgrade!

[ocelotbob]

Well, logically, a frozen system is a paragon of stability. Regardless of the network packet, regardless of the keyboard input, it retains the same usability, and the same functionality. In entropic terms, it's at its natural state, the lowest stable energy level. It is the act of booting that makes a system unstable, and the system's crashes and segfaults are the results of the machine working to return to this natural, stable state.

Re:Time to upgrade!

[msh104]

Also note: a few security flaws that are fixed in the 2.4 kernel are NOT yet fixed in 2.6, so even if it would already be rocker than rock solid. THAT is still a very good reason not to upgrade yet.

Re:Time to upgrade!

[Berzelius]

You haven't paying attention at physics class, even the so called 'stable' elements show a certain amount of 'decay'. p.s. I guess the fall-out here is the other OSs ;-)

2.5 has been largely successful, and a lot of end users were able to compile it. 2.3? That's another story. I remember not being able to compile 2.3 once.

Good job to all the kernel hackers.

Linus was quoted as saying "How many fuckin' browsers do we NEED, anyway?!?!?!"

Re:That's good

[GrenDel Fuego]

As long as you didn't need IDE anyways.

IDE was unstable/scary for most of the early 2.5 series. I believe it around around 2.5.40 or so when the IDE system changes were removed and things became usable again.

Re:That's good

Yeah, that happened to me once, but I was so drunk I could barely stand up. On my feet, I mean. Anyway, by the time I noticed what was (not)happening the girl was passed out, so it doesn't count.

Get what story straight?

A friend passed along a bittorrent link to me of a supposed hl2 beta, not the source, I've seen screenshots, so I'm pretty sure it's out there somewhere. But as I didn't actually try it first hand (I've got better things to do than dl a crappy hl2 beta), or talk to a trusted friend whom tried it first hand, I can't be 100% positive, so I put the disclaimer "from what I hear" on it.

I'd like to think I have a pretty good bullshit-o-meter, so I only pass along information that I'm pretty darn sure is correct.

Re:This month will certainly go down as

[jjhlk]

What did you see screenshots of? Demos? There have been quite a few released.

Supposedly the hacker behind it said he also has the beta, but I haven't seen any evidence. The source is quite easy to get though. And I don't know much about bittorrent kiddies nowadays, but fake warez are released all the time over sharing networks.

Re:This month will certainly go down as

[jjhlk]

Just read a story about leaked beta screenshots though, and saw the torrent link myself. Two Cds worth..

Re:This month will certainly go down as

[gid]

Most of the screen shots were actually of HL2 running in a window on some guys desktop, I suppose those could have been faked as well, seems like an awful lot of trouble tho just to try and convince people that there was a leaked beta.

Reiser 4

[agrippa_cash]

So it looks like we'll have to wait a while longer for Reiser4, or were some of the Reiser4 implimentation problems due to the shifting kernel patches? Anyone? Anyone?

Re:Reiser 4

[caluml]

More importantly, is XFS in there by default? I haven't tried it since about 2.5.59. It's annoying when patches made for vanilla 2.4 don't apply on 2.4 + XFS. If the vanilla kernel came with XFS, those patches would be made against that, and would apply.

Re:Reiser 4

[Anonymous Coward]

According to http://www.kernelnewbies.org/status/latest.html, XFS has been in since 2.5.36

Re:Reiser 4

[caluml]

Then the answer is yes. Reiserfs for lots of small files, XFS for lots of big files or its nice ACLs, and ext2 for that /boot partition. Ext3 over my dead slow body.

Re:Reiser 4

[Anonymous Coward]

Wise man. I have an entirely different setup, but I am the only user so it doesn't matter.

Here is something I think you will laugh at: I will soon be booting off a minix partition. I am not kidding here.

Re:Reiser 4

[Skeme]

Good question. It will appear in someone's (I believe AA's) tree in a couple months or weeks. From there it will stabilize and get added to 2.6. Here's the latest status update from Hans:

The filesystem is getting reasonably stable.
This weekend we hit a bug in space reservation, which we can't reproduce yet but probably isn't too hard to find by code inspection. There is some thought that the assertion not the space reservation is buggy, in any case we'll release a snapshot after it is fixed.

Our performance is generally wonderful and getting better.
It has the following weakpoints:

* We allocate a "jnode" per unformatted node in the filesystem. The traversing of these jnodes consumes more CPU than performing the memcpy from user space to kernel space when doing large writes. I don't yet really understand on an intuitive level why this is so, which is a reflection on my ignorance as it is consistent with stories I have heard from other implementors of filesystems who found that eliminating per page structures was an important part of optimizing large writes. We will fix this by creating a new structure called an extent-node that will exist on a per extent basis, and this will probably cure the problem. This will greatly simplify parts of our code for reasons I won't go into, and it will also take us 6 weeks to do it. I don't think users should wait for it, and so we will ship without it.

* Our dbench performance was poor, has improved due to coding changes, and we need to test and analyze again. Perhaps more fixes will be needed, we can't say yet.

* Our fsync performance is poor. We will pay attention to this next year, frankly, after we have fully implemented the transactions API. At that point we will say something like, if you care about fsync performance you should be using the transactions API and/or sponsoring us to tune for NVRAM, users will say back "but our legacy apps on hardware without NVRAM matter!", and we will grudgingly but effectively tune for this because we care about real users too.;-)

Nikita recently invented and implemented a clever bit of code that keeps track of the highest node in the tree that spans a directory, and then performs repeat lookups within the same directory starting from there rather than the root. This is a nice answer to those who keep asking me, wouldn't it be faster to have separate trees for each directory? Now I have better answer for them --- nice work Nikita. It also has the nice side effect of reducing spin lock contention on the root node for 4-way SMP.

I am hoping to move my laptop to SuSE 9.0 running reiser4 sometime this week, and I am hoping we will ask for more outside testers to help us find bugs at that time. While I have mentioned only the performance flaws in this email, our overall performance seems to leave little doubt that the filesystem as-is is far better than V3, and even though it will get much faster with another year or so of tuning, if now we are the fastest available on Linux, we should be shipping now (assuming we find no new bugs in the last round of internal testing).

Benchmarks can be found at www.namesys.com/benchmarks.html

As you can see in those benchmarks, in V4 tails IMPROVE performance due to saving IO transfer time. This is a great improvement over V3, and generally speaking V4 stomps all over V3 performance. It also scales better, has plugins, and improves semantics a little bit (big semantic improvements will be in the next major release not V4).
You'll also notice that we increased the size of the fileset to be more fair to ext3, and we tested some ext3 configurations Andrew Morton suggested testing.

Hans

Re:Reiser 4

[Anonymous Coward]

Crikey... You've got to be kidding.

You think Ext3 is slow and yet you stick with XFS? I've never seen a file system add so much bloat to a kernel. But that's not the worst of it, XFS chews CPU cycles like nothing else. It might be OK for a server with only a couple processes, but for general use XFS blows.

One of the reasons XFS is slightly faster is because it steals cycles from the rest of the kernel and processes. On a desktop machine it kills the interactiveness of the system.

My understanding is that since Windows NT is basically just Microsoft's OS/2 code from back when they picked up their toys and moved out of IBM's sandbox, that the numbering basically picked up from OS/2. Which still doesn't exactly explain the absence of a 3.0 release, nor is it a particularly honest and forthright way of numbering things, but, hey, this is Microsoft we're talking about, so what do you expect?

I honestly dont know.. but maybe someone can asnwer... was microsoft and ibm working on the os/2 3.0 code when microsoft split? If so.. they probably descided that their os should have the version 3.5, being that its 'better'. (In microsofts eyes, owned by microsoft means better.)

Either that, or they named it 3.5 because the non NT version of windows was 3.1 or so at the time?

Actually I think NT was supposed to replace windows back in those days.. but microsoft just couldnt get the market to bite (for whatever reason), and ended up... makeing do... (instability in NT? incompadible with most dos stuff?) They have been saying for years that NT was going to replace windows in the NT 4.0/Win 2000 days... guess we had to wait for XP =)

Stability?

[Wooky_linuxer]

When the 2.4 series came out, it was much criticisd for not having anything near the stability of the old 2.2 series (I'd say it haven't catch up yet,but since I use it in a desktop machine 2.2 is not an option)... What can we wait from the brave new world the 2.6 kernel will bring?

Re:Stability?

[efti]

I've been using the 2.5 series since 2.5.66 or so. The main reasons I recommend 2.6 are:

• Greatly improved responsiveness under heavy load -- I no longer notice cpu-intensive tasks like a kernel recompile or the slocate database rebuild cron-job happening in the background. And X isn't even running with higher priority.
• Built-in ALSA (Advanced Linux Sound Architecture) -- much improved audio, especially audio recording
• Improved ACPI power management and CPU frequency scaling (my main machine is a laptop)
• Software suspend (just like hybernate on Windows), again handy for laptop users, or those who like to sleep without listening to the whine of their super mega cooler CPU fan / vacuum cleaner attachment.
• Built-in IPSEC support. This is mostly useful for those who need to set up VPN tunnels. I imagine it is more efficient to handle IPSEC inside the TCP/IP stack itself

These are the ones I can think of off the top of my head. I haven't used the built-in IPSEC yet, and software suspend still doesn't work properly on my laptop, but it's not far off. 2.6 will be a pretty sweet series.

Re:Stability?

Re:Stability?

[wfberg]

More hypocrisy, like before. Linux can put out several filesystem corrupting kernel releases and major showstoppers as in the 2.4.x series, but if a user-transmitted e-mail virus makes the rounds, it's a "Microsoft hole."

Linux doesn't put out Linux releases, Linux is Linux. And Linux is used in several distributions - you can get a five nines Linux distribution if you like. Bugridden open source software does get flack -- distributions don't incorporate a kernel they don't feel comfortable with (RedHat's kernels are heavily patched for instance), no-one will touch wuftpd with a 50 ft pole, people wil nag authors with patches, fork or start competing projects (qmail, postfix vs. sendmail) etc.

Speaking about qmail and open source software getting flack, ever read DJB's comments on BIND and sendmail? Or ANY holy war? (BSD vs. linux, EMACS vs. VI,.. )

User-transmitted e-mail virusses? That's called a trojan horse. Recent worms -- exploiting holes on Microsoft's e-mail client running on Microsoft's operating system and Microsoft's browser -- depend on bugs and design in Microsoft's software and that's squarely their responsibility (e.g. why is RPC even listening to anything but localhost by default? If you needed it to listen to the entire internet, you'd know and could change the default).

Besides, those crappy kernels you mention haven't affected me one bit. Whereas I've spent quite some time getting people to install patches, firewalls, and remove those darned worms.

Some people may have a certain amount of unfounded (or at least, not founded in technical fact) animosity towards Microsoft, but let's face it, most mature open source software we rely on is much, much more secure, stable and well-designed than MS Outlook and its ilk. And that most certainly includes the Linux kernel. Comparing apples and oranges, maybe (the 2k/XP kernel isn't half bad either) but that doesn't mean that Microsoft should get away with crappy products that aren't kernels.

Re:Stability?

[Anonymous Coward]

Is this some kind of a joke? Do you have any idea how many Micorsoft file system corruption bugs have been reported since 1991? Even worse, MS has only ever supported 3 (fat,ntfs,hpfs) i/o file systems to Linux's 19+ i/o fs's. You don't have anything to brag about there pal.

Re:Stability?

[LearnToSpell]

I'd agree with what you said except for the ACPI/APM and software suspend stuff, which are totally broken for many, many people right now. Some major overhauls happening, so we'll see if they get done for 2.6.

Re:Stability?

I would agree on the server side. RH upgraded 7.2 to a 2.4 kernel and yes I gained iptables (even tho ipchains was adequate) but I did lose some stability. I still only have to reboot every 6 months, but its usually due to some unexplained problem that I didn't have with 2.2.x

Yes, I would prefer 2.4+ on the desktop, but I am considering doing a serious downgrade on a few dedicated boxes I have (dns in particular) due to my faith in the ability to crank out a non modular 2.2 kernel that you can't crash. Actually, until 2.4, I hand built every kernel and never used ANY kernel modules, building everything directly in.

Did you know that "Linux" is about 35MB of kernel source code only? Its not an operating system, its a freaking kernel. Mandrake, RedHat, SuSe and even Caldera are "Linux distributions". I installed several distributions in the 2.4 series, and at least a dozen different kernel releases, and never saw, experienced or heard about any file system corruption due to the kernel. Then again, most intellegent people don't load the freshest kernel on a production machine.

As a matter of fact, you don't change the kernel unless it has an errata that actually affects you, you need the new features, or you are foolish. At least with Linux, you have a choice of kernels. You show me a smart Linux admin, and I will show you someone using a kernel that is at least a couple versions back.

There are Linux viruses, btw. The difference is when a Linux box gets infected, it is designed with permissions that make it impossible to send it out to every other Linux box out there. Its by design.

Re:Stability?

[saskwach]

Okay, I'm probably being trolled, but I'll bite anyway:
When a new kernel release comes out, nobody forces you to use it. You don't see routers using the development kernel very often, now do you? The whole development cycle for open source software is vastly different from that of a proprietary system like Windows because the cycles are different lengths. I'll let you read about cathedrals and bazaars on your own time, but anyway, back to the issue. A kernel patch is something only a relatively savvy user who knows what they're doing will attempt. Windows worms, like lovsan, are not transmitted through any conscious action on the part of the box owner. In order to prevent them, the user has to be aware of what is going on security wise. Now, don't get me wrong on this, I read about the RPC hole that spawned lovsan and patched right away, as should most windows users, since there are auto updates...but an unstable kernel release that's called stable and sticks around for a few weeks is hardly comparable to a hole that existed, unnoticed, for about a decade. As far as your sig goes, do you see a site like that for Microsoft? Do you honestly believe their programmers are so much better that they have a significantly smaller error rate? A huge and open bug database in the open source world helps eliminate those bugs. I know, I know...troll, whatever, I'm sick of not ranting.

There was nothing 'random' about it, it only corrupted the filesystem if you did not sync your disks before you unmounted them. Which distributions like Debian have done in their shutdown/reboot scripts. Still it was quite a nasty bug. But you also have to remember not every machine, probably not even a majority of machines out there are running ext3. Diversity and choice in a kernel and in cases like this can be pretty neat at limiting the damage done by a borked kernel.

Re:Stability?

[Anonymous Coward]

Face it. All the Linux users will freely ignore and disregard corrupting kernel releases. If Microsoft even dared do something like corrupting everyone's NTFS installations, they'd be eaten alive by hundreds of fanatical posts here.

We can ignore the kernel releases that have had major problems because the only people who run them are the developers and the geekiest of the geeky Linux users already. The problem is then fixed before anyone uses, (hopefully), the kernel on a production system. The big difference here is that Linux is just the kernel, if Redhat released a distro/OS that caused massive filesystem corruption and major problems then people would indeed be posting here flaming RH for not testing an operating system and allowing major flaws of that nature. A kernel release is quite a bit different than an entire OS, you have certain expectations when you purchase/run an OS. Compiling the latest kernel on your system should not come with the same expectation of quality that you would expect from a full fledged and tested OS. But as we have seen with Windows 98a those expectations are not always met.

And those Windows problems have never, ever affected me.

Well you must be living in a different world than me. The bandwidth that all of these worms are creating affects my servers every day. I drop thousands and thousands of packets targeting windows specific flaws every day. I have to filter out the "install this patch!" emails that are propagated by millions of idiot Windows users. Thousands of those emails. When the blaster worm shut down the part of the US govt that was reponsible for Visas it cost tax money out of my pocket to fix it. Same goes for all the other damage done by these worms and exploits, (regardless of platform), it's money out of my pocket.

Might I also mention taking a look at my sig and seeing that OSS is just as full of bugs as Microsoft? Need I mention the "Linux Most Attacked OS" article Slashdot posted that linked to a study showing Linux as the most breached server on the net? Need I mention ssh/ssl? Bind? Sendmail? I could go on and on...

You know that that article was a bunch of crap, people have been responding to that every time that you bring up the issue, the group who did the study has been repeatedly discredited. How do you define breached? Did it count all of the thousands of Windows servers that were breached with blaster, viruses, and the other various worms that make the rounds? As for the vulnerabilities in ssh/ssl, bind, sendmail... exactly how many million computers were taken down by exploits for those vulns? How much damage was done? What percentage of people had their boxes owned thanks to those exploits?

First, in both posts I have looked at of yours, I noticed the use of the word "dummy". I doubt that either parties you are arguing with are dumb, let alone wrong in this instance. Calling someone a dummy because you made a mistake does not make your point any more valid.

Also, a kernel is not an operating system. Let's see you run just vmlinuz by itself. Or just load Kernel32.exe into RAM and see what happens. An operating system has a far broader reach than just the core (kernel) subroutines.

Next, I've seen Windows 2000 Adv Server corrupt it's permissions so badly that the only recourse was to reinstall the OS.

Finally, Windows 98SE had a similar bug where it shut down too quickly without allowing the heads to park and would ultimately self corrupt. I have a similar problem in Windows XP with my RAID system, I doubt I am wrong about why it happens.

Face it, you are defending an operating system, of all things, for reasons that aren't even valid, and getting all heated up for no good cause.

Not that I would want to get associated with that other troll, but how exactly do you suppose that Unix permissions or "design" prevent viruses from spreading? Last I looked, I could connect to Linux boxes all over the net quite fine using my normal unprivileged user account, there's nothing that would malicious code from doing the same. A virus doesn't need to run as root to replicate or anything.

In fact, the classical Unix security model with ugw/rwx permissions and the omnipotent root is pretty poor (granted, it is better then no permissions or mostly unused ones). Which is why basically every Unix-like OS is busy implementing extensions to it, like capabilities, fine-grained ACLs, MAC etc. I don't know about any Linux distro or other Unix that uses them sensibly out of the box, however.

I still remember the infamous Thanksgiving "turkey" kernel that randomly corrupted ext3 partitions.

Kernels from kernel.org are not made to be run by endusers. For that you want a distribution kernel. That's what the kernel team also says.
If you do choose to run a kernel from kernel.org, you are responsible yourself, and if you have problems, you should track patches yourself. It's also a good idea to do this in advance, or wait a week before booting a new released kernel.
Running a vanilla kernel with a bug like this is really a user error, you know....

Re:Stability?

[broeman]

I know you don't want to sound like a troll, but ignorance or misinformation typically create that image. I accept the fact that we need a better admin-system in *nices, since we only have root ... it should be allowed to be divided.

It is true that a virus doesn't need root-access to replicate itself on a network, but it need it to infect system-files, which windows cannot guard against. Like on a windows-machine, Linux users are also obligated to download a virus-scanner (eventhough I have never found any in the 7 years running a linux machine), which can be done for free (e.g. f-prot). Worms is another issue, and only a good firewall can protect against this (like on a windows machine).

Re:Stability?

[superchkn]

You're lucky you didn't start early enough to hit the test kernels that trashed the filesystems, but I think that was back in the 30s. I'm not sure because I didn't start testing until 2.5.69.

Well, it is a beta kernel, so things like that happen. I think the 4GB thing went on for a week. I've been pretty lucky though, I haven't had any panics, though I did with 2.4.18 (something about USB once).

Re:Stability?

[superchkn]

Face it. All the Linux users will freely ignore and disregard corrupting kernel releases.

Hmm, is that why they got fixed?

Seriously though, what you're failing to understand is that the things that caused those problems (such as ext3 corruption) as has been mentioned were "experimental" features. That's called beta. What that means is that only people who can afford to have their system hosed should be using it.

Let me explain that maybe in a way that you'll be more likely to understand. I have in my possesion a Windows 2003 RC2 CD. So, I install the CD and damn if I can't do a windows update! Or, when I try to start some of those services a message pops up that it isn't yet complete. Do I bitch about these features that aren't functional in the Beta as if this was software I spent $100 on? Why no, because I understand the concept of beta software.

Now when some new piece of hardware doesn't work with Linux, by all means complain...to the manufacturer of that device so they'll release the specs to the LKML. Or, if you have some other problem, post a friendly message to the LKML and offer whatever info the developers need to troubleshoot the problem (if it's the kernel of course). So basically, I pay $100 for my upgrade WinXP CD and it doesn't work worth a damn with my hardware and Microsoft isn't even interested in sticking some hard drive transfer mode controls in the control panel so I have decent performance. OTOH, if I have a problem with the Linux kernel (which I paid $80 for a distribution that came with every program I need), I can just find the developer site and they can help me fix it.

Granted there's some buggy open source software, but don't insult everyone's intelligence by claiming that there isn't any MS or other commercial software available that only sells because it looks good on the box. At least if I don't like the OSS version, I can just try another. Kinda hard to get your money back from the store after unpacking the software.

Re:Stability?

I know good Unix admins and good Windows admins and neither of them puts fresh stuff on production machines.

The base definition of an operating system is the kernel running it, dummy. Linux is the system operating my devices and letting me operate my computer.

I'd say the based definition of operating system is an abstraction layer between user applications and the hardware. Kernel is one part of this, but so are libraries and basic utilities. You could even say that "the Linux kernel provides hardware abstractions and device drivers for the rest of the GNU/Linux operating system".

Windows also has permissions. Every single Windows network I've ever run or worked with operated the same way.

I agree here. The problem is not that there was no permissions. Both systems have equally bad permission framework (and on theoretic level I'd vote in favour of Windows if I'd have to). Users have too much permissions by default, permissions are too limited and fine-grained, and programs run with the full priviledges of the user running them.

The main problem however, is how these systems are run, and whether those permissions can be enforced reliably. First is question of management, second is question of code quality.

Re:Stability?

[__past__]

Simplicity is great (and IMHO the lack of it is the biggest reason why newer features don't get used), as long as you can still do what you need to.

The biggest problem right now is the root user, IMHO. You just need root privileges too often, and in classical Unix, you either are root, or you are not. There is, however, no reason why my MTA has to be able to change everybodys passwords, write to raw disks, load kernel modules or modify packet filter rules just because it has to listen on port 25. Capabilities fix just that: You can grant a process the capability to listen on a port < 1024 without neccessarily granting it anything else.

File system permissions are less critical, but cumbersome. Imagine a file that should be readable by the members of two groups, for example. No easy way in classical Unix except creating a new group with the members of them both, and you have to keep them in synch manually. It gets worse if you want to make sure that people don't accidentally (or with malicious intent, but that is a lost battle in most cases) don't leak things they may legitimatly work with to others who don't. Mandatory Access Controls (MAC) make this possible, but it is a lot of work to set up - basically, you define a context of users, objects (like files) and processes to work on them that is hopefully safe, and the system forbids anything else - you might be allowed to view a file in a browser, but not to copy it to another file with different permissions, for example.

As I said, things like Capabilities or MAC are becoming more common. There are, as usual, kernel patches for Linux, FreeBSD 5 has this kind of things, proprietary Unixes sometimes have special "Trusted" versions with these features.

For more insight about the Unix models, I suggest reading some of the papers written by the Eros project, or the Unix Haters Handbook, where some Multics people talk about that. Asking VMS veterans can also be enlightening.

Re:Stability?

It's possible to create a 3rd group and grant members of those 2 groups with `sg` and a group password (or a setuid wrapper like sudo). I doubt many people would do this, simply because the vast majority of *nix users don't seem to have heard of sg.

Hmmm ... this is what "nice" is for.
In my .bashrc I have the alias:

alias make='nice -n 19 make'

And I can happily compile mozilla (or anything else) while doing whatever else I like (short of playing action games, since there will be occasional tiny lags, and if you're using 100% CPU all the time there's not much point compiling in the background, anyway) - for "normal" tasks such as programming, word processing and graphics manipulation you'll never notice any difference.

Likewise I encode divx files at nice -n 19. It never ceases to amaze me how many long time users don't realise you can run tasks at lower priorities ...

The patch you're talking about sounds impressive, but I can't really see why you'd need it for background compile jobs. And while I have a nice AthlonXP system now, until recently I was doing exactly the same things on a 500 MHz celeron and never had any problems.

Re:2.6 seems unimportant for me

[nsingapu]

I havent touched 2.6 with my desktop boxes, but for my (relatively cutting edge, broken bios) laptop its ideal.
Some months back when my laptop shipped ACPI would freeze on 4 or 5 vanilla and patched kernels I tried the exceptions being late 2.5 and ac series kernels.
Though the situation is better now I find 2.6 irons out some minor stuff with reiser performance(which I cannot duplicate on other hardware, and have yet to find information about, boot time was ~10 min largely due to checking reiser at boot), allows working acpi and b44 drivers (these have largly been backported), and perhaps most importantly has richer facilities as far as acpi sleep states, swswap, and powersaving feature in general go.
As far as snappier schedualing and the like this is icing on the cake but, to me atleast, not as mentionable as better support for my hardware.

Perhaps the an interesting aspect of the comparison of new features in 2.2->2.4 and 2.4->2.6 is reflective of and specific to linux on the desktop, with 2.4 catering to features lacking in desktops (usb, firewire) and 2.6 adding quite a bit of stuff specific to mobile use.

Re:2.6 seems unimportant for me

[superchkn]

It never ceases to amaze me how many long time users don't realise you can run tasks at lower priorities ...

Actually I know about nice... I was using it more to make a point about how much better the scheduler is with the Con's patches. It's a lot easier to start up a compile than it is to duplicate a repeatable situation across a range of machines where the patch makes a difference.

The patches were made to improve interactivety, which means the scheduler tries to guess what processes are interactive (i.e. important to the user), and what processes are CPU hogs (i.e. dnetc, gcc, etc). This allows one to run audio players (i.e. XMMS) without skipping even under a high load (say mozilla churning on some javascript). This is more a patch to help the behavior of tasks that are usually interactive but become cpu hogs and vice verse. So in the case of Mozilla, I don't want it to run niced, but I also want to be able to switch to another window, or type in another window when it hits something that takes a while to process and have my system be responsive. Or maybe even I want to change tabs in Mozilla, that doesn't work so well when my mouse is stuttering across the screen because Mozilla is hogging the cpu.

I haven't booted 2.4 in months so I can't directly compare 2.4 to 2.6, but I can compare the vanilla scheduler without Con's changes to the one containing them. I do know that versus 2.4, this also prevents the need for running X at -10 like some distributions do, which hence reduces the risk that X starts hogging the CPU for some reason and effectively takes down the machine. I can't say I've ever had that happen though ;-), but SuSE 8.0 doesn't run X at -10 anyhow.

The 2.4 scheduler is a much different beast than the one in 2.6, though I'm admittedly not clear on what all problems it allegedly solves. I've listed some, but there are other advantages of the changes, you'll need to search the LKML archives for more info.

Re:2.6 seems unimportant for me

[the_2nd_coming]

well, the old Scheduler is a liniar scheduler, O(n),

the more you throw at it, the more boged down it gets.

the new scheduler is a constant time scheduler, O(1), which means that it does not get boged down the same way the other scheduler did...obviousely, the more you throw at it, the more things will have to share the system, butit should not allow for freeze ups.

I was using it more to make a point about how much better the scheduler is with the Con's patches.

Fair enough - I'm not disputing that the scheduler is not vastly improved, only that you didn't need those improvements to successfully compile stuff in the background ... The other examples you've given make more sense.

I was just ranting about how useful nice is, and yet how little use seems to be made of it ...

Re:2.6 seems unimportant for me

[superchkn]

Yeah, I should have given a better example or qualified the context in which I was using compiling as an example.

Certainly it would make much more sense to use nice rather than change the kernel just for the case of compiling ;-)

I was just ranting about how useful nice is, and yet how little use seems to be made of it ...

That's probably more true now then ever as more and more people switch from non-*nix systems. Luckily the 2.6 kernel will help hide the error of their ways better than it has in the past...all without an ugly kludge that boosts the priority of the focused window process.

Re:2.6 seems unimportant for me

O(1) shouldn't have much effect on the desktop...

comming soon...Random reboot module...just to keep up the Windows look and feel...

In pratice

[rf0]

I've been using 2.6.0-test4-mm4 daily without problems. No glitches. The 2.6.0 kernel has real improvments in the shape of Alsa being mainstream. Also the I/O schedular + interactivity is much better under load than the 2.4 kernel.

Of course however I won't be putting 2.6 into production use until at least 2.6.8 or there abouts to make sure there are no nasty surprises in there

This is true, I didn't use 2.4 till 2.4.8 or 9. Probably won't use 10.2 till 10.2.8 or 9. :)

Re:Blah blah

[Anonymous Coward]

Well, first, increase your expectations ;-)

I've not had such luck with XP as it lumps most everything onto one IRQ and then stutters as 6 devices fight over the same IRQ. The MS provided NEC USB 2.0 PCI card driver likes to BSOD too. I expect the OS to be able to handle a machine stuffed full of cards (AGP, 4 PCI, 1 ISA).

I'll admit though that from test3 to test6, the 2.6 kernel no longer acknowledges my BIOS setting that's supposed to keep PCI cards off IRQ 5 (for my ISA soundblaster), but I can live without sound (not to mention this is a beta and my problem is logged). I can't live with an OS that constantly stutters about and crashes all the time, which is what XP does.

I don't think that's a troll either. The i/o has gotten really smooth and snappy. Other than that, it's certainly not a mandatory upgrade. The rule of thumb is pretty much to run the kernel which was stable around the time your PC was purchased. If the server is still stable, no need to upgrade. :)

Modular source code?

[pjack76]

How difficult is it to only download those kernel modules I actually want to compile? As time goes on and new stuff keeps getting added to the kernel the source just gets out of hand. Someone should set up a little webby clicky thing that's like "make menuconfig" but then assembles a tarball only containing your precise configuration and those modules you've selected. Just a thought.

\\k

Re:Modular source code?

[pi_rules]

Whoa.... that's friggen cool. Seriously.

Most of us have big pipes for bandwidth so pulling a 22MB kernel archive isn't that big of a deal. Sure, it takes some time but we can do it and live with a 5-10 minute delay.

This idea is just waaaay geeky though, and cool. It would have to be a distribution specific type thing though. There's no way I'd expect the kernel maintainers to take on this task -- it's just not their style.

Debian could, with some work, create a 'kernel-source-2.6.0-skeleton' package though with modified Makefiles that would wget the source files if needed at compile time. That could be friggen awesome. You'd just nab a 200k skeleton package and as it compiles it'll start snatching files. With a little script-fu pulling header files from neccessary .c files should be a piece of cake.

I'm tempted to say that this might cut total bandwidth down by half, maybe a quarter... which after the efficienty of a .tar.gz of the whole thing might not net you much in saved bandwidth. However, it would just be plain -neat- to have only the .c and .h files absolutely neccessary for your particular build. No matter what file you open from your kernel source tree you know for sure that it has an impact on the actual build of your kernel. If you modify something from such a system you know your binary output is going to be different. That is, barring GCC optimizations and such. If you turn the line 'c++' into 'c = c + 1' you won't net a binary change.. hopefully.

Super cool idea... what else could this do?

Well, instead of having /usr/src/linux-2.6.0 you could just have /usr/src/linux (not just a symlink mind you)... and the scripts within there would have enough know how to automatically pull the most up to date code and such. Lets say 2.6.1 comes out:

cd /usr/src/linux
make oldconfig && make

Sha-zam! You're pulling 2.6.1 code (what has changed at least)_and rebuilding.

I like the idea. Go code it dude. :)

Re:Modular source code?

[MBCook]

While a neat idea, I think that it would be very hard to implement, and the tradeoff isn't a good one. What tradeoff?

Well, the patch for -test7 is just over 650k if it's bzipp2ed. While it would save space/time/whatever to only download a i386 version (no PPC code, etc), or a version without all the sound code (I'm making a server, I don't need that...) etc, you run into a problem. Just what are you going to do? Let's say you have 4 architectures, the sound option, an ISDN/amature radio option, some PPP/dialup stuff in an option, and two others. That's 4x2x2x2x2x2, or 128 possible combinations of kernels. Now there are more than four architectures, and there are probably some more things that could be put into downloadable options.

So, are you going to do everything through CGI scrips that fetch the right one? Are you going to use those scripts to package and test each of the possible sets of options to make sure no important code gets left out? Is it simply going to be a single choice: x86 or "other"? Do you want to move things like sound to external patches like ALSA has been for such a long time?

Really, I don't think that this is worth it. It's a neat idea, and if you want to make some things available on your personal website or something like that, go ahead. More power to you. It's a good idea. But for it to be "official", just seems like too much of a hasle.

Re:Modular source code?

[surprise_audit]

Sounds rather like the NetBSD (and others) way of building the kernel. You take the generic config file, which has all the really common/useful options already selected, then you pick the various bits you want and comment out the rest. Once you have your custom configuration, you run the config program against it. This creates a compile directory that contains symbolic links to the necessary source files, and probably fiddle with Makefiles, etc. You cd to the compile directory and run make. Some time later, you have a kernel.

Now, suppose the "symbolic link" stage was replaced by a wget-if-newer, pulling the source files from the official source tree...

Of course, this would only really work with the standard source tree. If you wanted to be able to add any random patch sets, the config program would have to be a lot smarter.

Re:Radeon FB fixed?

[fishbowl]

Yep. I've been a hawk for every bit of information I can get my hands on. I don't think a fbconsole on a Radeon 8500 LE should be this weird of an order. (I know, the devteam cannot test every combination of hardware, yadda, yadda).

If I have to buy another video card just to upgrade the linux kernel, I want to know precisely which one will give me satisfactory fbconsoles ahead of time, and I will write it down in the TCO-margin column.

When I get time, I will install the latest 2.6, regress through the various patches for radeon, and see if the problem has magically gone away.
I don't know a good way to characterize the effect though. You run fbset to a high resolution, and end up with a console on 1/4 of your screen and various garbage on the rest of the screen, and general instability.

It doesn't seem like very many people are using fbconsoles and it certainly doesn't seem like the people developing the ATI drivers have their hands on very much ATI hardware. I know, volunteer effort, yadda yadda, but is it a mature OS with a huge developer base and widespread adoption? I figure this will probably get fixed before 2.6 comes out, but if it doesn't, Radeon cards shouldn't be on the compatability list for it.

Re:Radeon FB fixed?

[lintux]

Tried -test7 on my iBook (Radeon 7500) last night, it worked perfectly. Didn't need to use the OpenFirmware framebuffer anymore. :-)

MatroxFB was still broken (in -test6 at least) though. But that might also be a configuration issue.

Re:Radeon FB fixed?

You probably know this already, but if you have some time to spare and know your problems haven't already been reported, and you're willing to follow up, try patches, etc., it'd be worth sending a message to lkml with all the details. That's one of the ways developers manage to keep the kernel working on hardware they don't have direct access to.

I think what he's saying is that on the 2.4 kernel, you can just run "make install" and it will do the lilo stuff for you, whereas with grub you have to do a "cp arch/i386/boot/bzImage /boot/bzImage.ver" or whatever it is you do exactly.

It's possible to set it up so that you can access it properly, but to boot from it would be a bit tricky. You'd need to use dm-setup from the lvm tools, together with a config file all wrapped up in an initrd image.

Don't you know that Windows does fake copying and actually copies in the background? It is really annoying on removable drives, and its dangerous.

That's called buffered I/O and is a standard feature of modern operating systems. Where it gets dangerous is that Windows doesn't force you to manually unmount removable disks before pulling them out, which can easily result in data loss. But that's what the little light is for next to those drives. If the light is on, don't take the disk out or you will lose data.

Oh, and always stop the hardware before removing USB or firewire storage devices as on Windows that's the only way to be sure that all the data has been written to them.

Re:Blah blah

Hmm, well there's no denying since it is built upon a VIA platform, throwing expensive hardware out will get nowhere.

Here's my cat /proc/interrupts under Linux 2.6.0-test4 (distribution is better with test6):

0: 181902735 XT-PIC timer
1: 131259 XT-PIC i8042
2: 0 XT-PIC cascade
5: 336866 XT-PIC ide4, ide5
7: 311 XT-PIC parport0
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
10: 21004082 XT-PIC ide2, ide3, ehci_hcd, ohci-hcd, eth0, radeon@PCI:1:0:0, km_ati (Radeon)
11: 41 XT-PIC ohci-hcd
14: 1 XT-PIC ide0

So, to satisfy you, let's go through this...
ide0 = VIA Primary IDE for IDE ZIP (no dma = no worries)
ide2 & ide3 = Maxtor Ultra133TX2 (i.e. Promise PDC20269)
ide4 & ide5 = Maxtor Ultra133TX2 (yet another)
ehci_hcd, ohci_hcd, & ohci-hcd = Belkin USB F5U219
eth0 = 3COM 900 Combo
radeon = ATI AIW 9000 Pro (this actually uses 2 IRQs, one for normal graphics, one for the tuner/video capture)
Not shown of course is my SB16 which takes IRQ5, usually which puts ide4 & ide5 on IRQ9

Windows uses things a bit different, IIRC it does things pretty much the same as kernel 2.6.0-test4 (but doesn't work well at all).
2.6.0-test6 does this:

0: 242690 XT-PIC timer
1: 313 XT-PIC i8042
2: 0 XT-PIC cascade
5: 70 XT-PIC ide4, ide5
7: 1 XT-PIC parport0
8: 2 XT-PIC rtc
9: 0 XT-PIC acpi
10: 47 XT-PIC ohci-hcd
11: 85 XT-PIC eth0, ohci-hcd
14: 1 XT-PIC ide0
15: 5780 XT-PIC ide2, ide3, ehci_hcd

Notice I didn't modprobe radeon so I'm not sure what IRQ it is on, but it's probably safe to assume it takes IRQ 11.

Anyway, when something uses the video card heavily, it knocks out the USB card and all the devices on it reset I guess (my APC UPS monitor says that the communication was lost, and my Mx700 receiver blinks the green like as if it was just plugged into the USB port). My Epson scanner and Brother printer/scanner seem fine. If I try to capture video, the mouse continually re-connects which makes it nearly impossible to manage the pointer's position. Same if I'm transferring a large file on the disk.

I also have problems with the Promise cards and my Maxtor 92048D8 drive which don't seem to get along in UDMA2 when writing. That's easy to fix in Linux either by doing nothing and letting Linux automatically put it in PIO 4, or by using hdparm to stick it in UDMA1 which works (this is a problem with the card/drive combination, not the result of a problem with the drive/cable/etc). In windows, on a write I'm greeted by a continual resetting of both ide interfaces on the card until windows has managed to transfer the file, which makes the 17MB in 2 minutes comment by that linux troll look quite realistic. The copy of Windows 2003 RC2 I have puts the drive into PIO 4 when the write fails, but XP does not do this. MS is not interested in solving it either, I used up one of my support requests trying to get them to fix it. Unless Promise adds the ability to set the transfer mode in their drivers, I'm stuck with high CPU usage and slow (0.25MB/sec) transfer rates under Windows XP. At least it isn't my boot drive, but I did partition an 18GB FAT32 partition for sharing files between Linux and XP with only 4GB on the newer Maxtor drive so I can't really install much on XP.

So yeah, XP works great if...

Re:BSOD module

[Anonymous Coward]

I don't know, since BSODs are a thing of the 90s, and most Slashbots are stuck in the last decade as they use a BSOD as their only desperate attack against a Windows world that moved on four years ago.

Granted, BSODs are kind of retro today. But I like my Atari 2600 emulator and my C64 emulator! And some times I have a strange appetite for BSODs, and then I fire up my Windows emulator and enjoy this jolly blue screen.

Re:Blah blah

Whoops, forgot to mention that XP nukes my net card so that I have to reboot to get it to work. Even then, I have to unplug the cable from the card for a while to get it working again even if I boot into Linux. That doesn't happen real often though, perhaps every 4 hours.

Meanwhile running a *beta* version of Linux:

Re:BSOD module

[Pharmboy]

But then again, Windows doesn't have a DLL for kernel panic either. I am not sure if its because the Windows kernel is apathetic and simply doesn't care or what.

On a lighter note, back in the windows 3.1/Lantastic days, I used to mess around with a program called "The Draw" (i ran a bbs, figure it out or google it) which could turn an ANSI screen into a .COM file. I would create a false BSOD that would say something along "Windows has detected a dumbass on the wireless end of the keyboard. Please use a pencil and paper instead" and place this in autoexec.bat, just before a "pause >nul"

The funny thing is half of them would tell me they have a "blue screen thingy" without reading it, giving me the opportunity to ask them "what does it say?". Its much more fun to hear them actually read it out loud over the phone intercom.

• back on kernel 2.4.23 - As pointed out by another poster, 2.4.23 isn't out now, so you couldn't be "back in 2.4.23", especially in July.

I'm sure that you have been setting up X on various distros for the last 10 years on many different video cards. All of your insightful comments on Linux, (jesus h christ man, almost 2000 comments already?), really show your expertise in that area. But have you ever heard of Mandrake, Redhat, Lycoris, Xandros, etc.? If you can't get X setup on any of the various video cards you've claimed to have used over the past 10 years then you are an idiot, plain and simple. The autodetection of hardware in those distros is good enough to detect the video cards across many years worth of boxes. X being tough to setup is a straw-man, even on Slack and Debian the toughest it gets is running xf86config.

Serious question...

[Cable_Monkey]

We are currently having some serious problems with our mail/web server. We aren't sure what is going on with it, but I'm not ruling out the possibility of being hacked. We were planning on upgrading the server to the 2.6 kernel and installing some hardware upgrades around Christmas time, but it looks like we will be forced to do at least the hardware part (and reinstallation of the system) this weekend. This machine operates on dual 1.3GHz Pentium III processors. My question is, do you think I would have any problems running Linux 2.6.0-test7? ...or should I just stick with 2.4.x until we decide to redo things again...probably in a few years?

Thanks in advance for your opinions.

Re:Serious question...

[Creepy Crawler]

Since what you describe is production, I'd advise to keep it at 2.4 .

If you wanted to, you could mirror data out so that there's a 2.6 mail server in testing.

Even that as a mail server, there's little reason to go towards 2.6 . The user-space and driver config (addition of /sys and other noticible improvemets) are probably of little value for a mail server. A client computer would benefit trmendously fro the additions made in 2.6

There is 1 feature that you could use: NSA security patch. It's in the "Alternate Security Model" part of the kernel. With those patches, it could make 'root' harmless. Since they've been back-ported into 2.4, it isnt much as a reason to stay with 2.6 .

Re:Serious question...

[Cable_Monkey]

I failed to mention this, but all email is accessed via SquirrelMail. We also use Amavis to scan all incoming and outgoing emails for viruses. Both of these combined during the busiest part of the day seems to keep the server quite busy load-wise. I was thinking the new scheduler and job spool methods would help manage things a little better. Now don't get me wrong, the current setup is not terrible, but I am looking for improvements.

However, given your opinion, I will stick with 2.4 for now. Thanks for the info.

Re:Serious question...

[Creepy Crawler]

As I reccomend not to go to 2.6test branch now, wait a few kernel versions: perhaps 2.6.3 and then have a test box to determine what you think is correct.

I do know that both (job and spooler) have been 'improved', but how that equates to the real world is only solvable by testing. All I know is testing a new beta kernel gives me the willies. you know.. the same feeling when you put a "patched" windows server on the external network

Re:Serious question...

[Anonymous Coward]

If you doubt him, you might want to subscribe to the LKML and see just how many security updates for 2.6 go by in a week... And some of these are very similar to the ones found in older 2.4 releases.

I wish I could offer direct links, but I'm pretty sure there were security announcements for 2.4.18 even. That's supported by the fact that my yast2 update a few months back updated the sources for my kernel. I don't remember what the problem was though...

Re:Serious question...

I'd rather try new hardware before doing that. As long as just the usual server-software is running (apache, mail-server), well - it does run on many systems quite fine, so chances are big it really is a hardware problem.

ACPI on Linux has a long long way to go. The official line last time I checked was that there were so many not fully documented ACPI implementations that they couldn't possibly cover them all. This of course is hard to argue with. At the same time its defintely a bit of a letdown when you consider how well linux is doing these days regarding hardware support. You all don't know how easy you have it compared to how it used to be.

For anyone who wants to use Linux on their laptop make sure and do your research. I'm not saying that's its not possible to use linux on your laptop(duh I'm typing this from my RH laptop) but realize that it may take a bunch of work to get all/any of the acpi features to work as well as they do on Windows.

ACPI bugs me. My last machine was a Via 133 based Duron. It would do S3. I had a Via333 based one for about a week before I gave up on it as being unstable and shitty.

It refuses to do X if ACPI is even turned on in the kernel. It stays on and running 24/7 under linux rather than napping like it does under windows :/

Keyboard issues are still not solved

[chrysalis]

No 2.6.x kernel ever worked with my keyboard (tried to various hardware, just the keyboard was the same).

The keyboard is a Logitech Cordless Pro (ps/2, not USB).

With a 2.6.x or 2.6.x-mm kernel, the keyboard works a by oddly. A single key stroke can produce 20 characters. Or sometimes 0. It's very irregular and using the keyboard becomes impossible.

I had no problem with older 2.5.x kernels nor 2.4.x kernels. No problem with OpenBSD either.

It's a real pity :(

That's called buffered I/O and is a standard feature of modern operating systems.

But that's what the little light is for next to those drives. If the light is on, don't take the disk out or you will lose data.

Unfortunately, this doesn't help for network drives. And they put the lights of the networking cards on the back of the computer. Those bastards ...

I would suppose this is to get a clean break from the mess (so I've heard) that is the current IDE code.

We don't like to complain about the Linux kernel because we don't pay for it but I was getting very frustrated at new things being included while existing bugs (like usb-storage and datafab CF card readers) were not being addressed.
Let's hope that the kernel ships with nothing broken.

D,

Re:Blah blah

Well, like I said, it's VIA hardware, so even top-quality hardware won't solve the problem. Still, it works fine in Linux...so shouldn't XP too?

No, K6-2 = MVP3
It's a shame it took me 3 years to figure out that the VIA IDE controller was randomly corrupting my data. Unfortunately this wasn't well documented or announced anywhere.

When I presented my conclusions to the LKML mailing list most people responded that they didn't have any problems. But 4 days of memtest86 and >12 hours of copying files and md5sum'ing them after each copy in every DMA mode/feature capability the hard drives support doesn't lead to any other conclusion. Luckily the chipset doesn't seem to be cursed with those busmaster problems. In Linux and windows though the VIA USB would make me re-connect my mouse (much like windows does now) all the time so I replaced it with the Belkin USB card.

Re:Blah blah

Sort of. I could run 2.4 which does work with my soundcard, but I prefer the 2.6 kernel since it supports writing to my CDRW without ide-scsi (and therefore with DMA).

Ah, before you jump in with "you could do that in Windows", I beg to differ. The particular LG drive I have, although quite recent, doesn't support UDMA. So on the Promise PDC20269 and subsequent windows drivers (including the latest driver and BIOS updates from Promise) it gets stuck in PIO mode 4. I probably needn't tell you how badly it burns CDs in that mode. It'd probably work fine for CDRWs, but with CDRs burning at a higher rate (> 12X) it slows the system to a crawl though it does have that superlink feature so at least it doesn't make coasters.

I've got a CD-changer and a CDR, plus I don't game much, so I can live without a sb16 which isn't known for its audio performance in the first place.

Oh, and I avoid XP because it likes to corrupt the registry when it does those beautiful BSODs. So I only use it when I have no other choice (i.e. vector graphics/Adobe Illustrator).

But basically, XP has just been a thorn in my side and I can't wait until I can ditch it for a Mac to use as my wife's graphics platform.

Re:Blah blah

[Anonymous Coward]

Well, they're all 2.1 capable cards and it's enabled in the BIOS. And Linux shares them just fine, did I mention that?

I think the real problem is either the driver for the Belkin card (I'm using the version from SP1, so I'm sure it's WHQL approved), or the ATI Catlyst 3.7 drivers. I changed to the VIA 4.49s but that didn't make any difference so I uninstalled them. (If they don't have everything working for a VIA MVP3 by now, they never will.) So, it doesn't work so well and there aren't any newer drivers to try...

Well, if we're talking about all-time uptime, then I'll have to go with 84 days 5 hours in Linux (as configured today, with a 3dfx banshee rather than the radeon) versus 6 days in XP (which really was a miracle since that was with the onboard VIA IDE -- note this was with only 2 PCI slots filled and nearly no use). However, I was speaking about my current uptime, which I'm sorry to say that XP cannot meet on the same hardware because it will die with a BSOD first. So, let me translate that for you, it's called "relative" not "subjective".

But yeah, I'm impressed your computer stayed up so long. BTW, I seemed to miss the part where all the slots are filled. I hear that makes uptime a lot harder to achieve...

Re:BSOD module

[mark_lybarger]

you've got to share some of that you're puttin' in the pipe, please. MANY, MANY folks have used X from a distro out of the box with no issues. the video card/distro does matter to some degree. Tools like xconfigurator or other vendor specific tools help the issue A LOT.

i agree that intense X configuration file changes can be a beatch, but come on now. 10 years, with common video cards? and you can't get X to work? share the "wealth"...

So I guess its too late...

Re:Blah blah

I changed to the VIA 4.49s

'Nuff said. Via boards are notorious for stability problems under XP (just see the microsoft.public.windowsxp.* n/groups). You don't have a Soundblaster Live, do you? That and Via is a losing combination..
Here's a nickel. Get yourself a proper chipset. Like anything with "Intel" written on it, for a start..

Re:BSOD module

[Izago909]

Ha, ive had W2K BS a few times this week, and my XP box *loves* to spontaniously reboot.

That's the 2000/XP BSOD. Miscrosoft was getting upset how BSOD was quickly becomming part of the technology lexicon. Their solution was to automatically reboot after a BSOD. Usually, it reboots faster than the monitor can draw the entire screen. The option can be removed so that the system freezes (req. hard reset) after a BSOD. I can't remember the exact registry setting, but one program I use is X-Setup. It's a freeware app that puts the TweakUI powertoy to shame.

kernel freeze stable?

[Tukla]

I suppose so. My computer has always been very stable after the kernel froze.

Well, I was able to get 2.6test 4 compiled and working on my box, EXCEPT for the bloody NVIDIA drivers!. Stuck in text mode - couldn't get X up and running, even afer DLing those patches from that german site for the NVidia stuff.

Sigh....... I'll guess I'll have to wait..

Windows XP only crashed once on me. It hasn't had a place on my hard drive since.

Re:BSOD module

[superchkn]

You can also just go into the Control Panel, System tab I believe and then click on the button about error reporting and recovery. Then you can change how long it waits before rebooting after a BSOD. I set mine to 5 seconds so I can keep score between which driver is causing the most ;-)

It's not like I ever expect them to be fixed, so I might as well make it a game. Kinda like, wonder how much code I'll lose this time...

I, too, am an early adopter.

[Anonymous Coward]

I can't wait for the 2.6.12-rh5 kernel. Don't think I won't have backups on hand when I do it though.

Actually, I'm sure it will be okay, but there is little reason to change. 2.4 promised so much, but after firing up my cyrix 233 with 2.2.12 a while ago, I realized what simplicity has going for it. I don't think I've ever used USB, and anyway, it's been backported since 2.2.19 I think.
