Kernel Bug Means Linux Power Usage Remains High 179
An anonymous reader writes "The significant Linux kernel power regression reported back in April, which ended up being attributed to PCI-E Active State Power Management, is still not resolved even as Ubuntu 11.10 and Fedora 16 approach. Until Linux is able to handle ASPM in a manner more like Windows or the device drivers explicitly set the ASPM flag, users of many modern laptops need to use the "pcie_aspm=force" option to regain much of their battery life. At least a power bug affecting newer Intel hardware with the "energy performance bias" feature has been fixed. There's more information in this LaunchPad bug report and in the latest power consumption testing."

It's a motherboard issue. BIOS supports ASPM but doesn't advertise it => Linux doesn't try using hardware that isn't there => power usage goes up => Linux gets blamed. Fucking Microsoft.

And this sort of thing really ought to be used to slap MS upside the head for behaving irresponsibly.
Wow, I knew someone would find a way to blame Microsoft for this... but so early in the thread - well done! Hey, there's a little girl missing in the Los Angeles area - could you find a way to blame Microsoft for her disappearance as well?
It's like the "Six Degrees of Kevin Bacon" game, but for Linux fanboys!
