Nailing the Cause of Recent Linux Power Issues

Posted by timothy on from the building-a-better-eyeball dept.

An anonymous reader writes "For the Linux kernel power regressions that were found a few months ago, and hit in Ubuntu 11.04, Phoronix has found the regression that's still present in the Linux 3.0 kernel. The power regression is caused by a change in ASPM, the Active-State Power Management, for PCI Express support."

    The user is not going to give a shit. The user will see that Windows doesn't suffer from this increase in power consumption and will decide that Linux is inferior.

    Phoronix guys weren't able to improve power usage by more than 15% even on this laptop, so it's not a big issue anyway.

    15% from 6hours make it roughly one hour so I cannot say this issue is really minor. I'd even dare to say that every such detail does count since most hardware vendors tailor their products exclusively for Windows and the fact that Linux even works is a wonder.

    And please don't judge Phoronix harshly. It's one of a very few websites which actually drive Linux development. Yes, Michael likes sensational style, but then again he wants to eat, buy hardware to test Linux on, pay for other people's work.
