Tracking Down The AMD "Processor Bug"

Posted by ryuzaki0 on from the complex-causes dept.

tercero writes: "over at the Gentoo Linux website there is an update on the AMD processor bug mentioned here. The sum up is that AMD claims it's not a bug with the Athlon processor, but with the motherboard. More detailed information can be found on this LKML post." An Anonymous Coward points to a similar explanation at Linux Weekly News. Update: 01/25 01:25 GMT by T : Daniel Robbins from Gentoo clarifies: "AMD is not calling this a 'motherboard' issue, it is an interaction between a feature of the Athlon called 'speculative writes' and the design of the GART, which is not cache-coherent. It's a 'Athlon/cache coherency/GART' problem, not a 'motherboard' problem."

  1. What is the exact parameter to pass to LILO? by Greg151 · · Score: 0, Offtopic

    I have seen both mem=nopentium and
    append mem=nopentium.

    Do I need the append or not?

    Thanks,

    That's because, unfortunately, the Mac is dying. Don't get me wrong, Steve Jobs has done an outstanding job in the last 12 years pulling Apple out of a dark crevase, but it's too little, too late.

    Mac OSX isn't making the kind of surge they had hoped for. Pre-sales of the new iMac are low (although the machines are really cool!), and with so little market share to work with, Apple's fate is sealed.

    Even Time's review was less than glorious, and had a very ominous feel to it.

    Too bad, too. I kind of like the fruity little buggers.

    It's an OS bug if you think that the OS should be bright enough not to make AGP-touched memory cacheable (it wasn't intended to be).

    I'm voting for option 3), myself.

    I think this revelation makes this parent worthy of being modded up.

    How do I block these page lengthening posts?

    The really sad thing is we have this wankerish little friends/foes system, which only puts nicely coloured dots next to someones name, but we still can not choose to ignore a user!

    Not sure about the MS Word thing, but I'd say your Diablo II crashes are a Blizzard issue. I've had plenty of problems with that game; lots of crashes, mostly, although crashes are a lot less severe and a lot less frequent with the current patch. The most irritating problem, though, is that my Play disc is unreadable by my DVD drive. This forces me to use my 4x8x CD-R (that's right, no -RW) which is painfully slow. I suspect it's the totally ineffective copy-protection that's causing that particular problem.

    Doesn't work if you surf below 0 because CmdrTaco has told us that if you surf that low you don't deserve to be able to filter out posts.

    I think he's wrong (and it isn't the first time -- see my sig), but hey, I don't run the site.
