Linux Kernel Suffering Power Management Regression?
An anonymous reader writes "It appears that there's a big power management regression in the Linux kernel for the 2.6.38 and 2.6.39 development releases, including the kernel to ship with Ubuntu 11.04 next week. It's reportedly causing a 10~30% increase in power consumption on many laptop computers."
This is presumably not an intentional regression though, more likely just some new/updated code that is causing the CPU to be more busy when the machine is effectively idle than it was previously. It isn't like someone said "hey, Linus, do you mind if I make the kernel eat more power?"!
Ever notice it is only Phoronix reporting that?
When did steam come to linux again?
Sorry, but I want to see this backed up another source before I just go believing it.
Would be handy if the suite (or the user) would actually produce graphs with different enough colors to make sense which line is which...
I'm on .38 on multiple computers and I'm not seeing these issues, perhaps it's a configuration error on their end (assuming they compile the kernel themsleves for testing) or a configuration error on whatever distribution they test with?
Ever notice it is only Phoronix reporting that?
Do you know of any other organization with a large automated regression testing system for linux kernels? That's not just me being snarky, its a serious question - who else beside phoronix is doing this sort of wide-scale testing on a constant basis?
When information is power, privacy is freedom.
Phoronix is shit. Pure, grade-A shit. Worthless.
They have _nothing_ of value to add to anything. Sensationalist crap which is not reported elsewhere, _because it it not an issue_.
Regressions in the development kernels are part of the process. Even actively trying to avoid Phoronix, I have seen tons of those non-news about some random regression and the breathless follow-up that, lo surprise, they didn't just release but fix the issue. Woooooo!
Phoronix is shit and it should be blacklisted globally on Slashdot and anywhere else. Stop linking to them, stop commenting on them (other than making others aware of this).
Rant over.
