Linux Kernel Suffering Power Management Regression?

Posted by Soulskill on from the year-of-linux-on-the-coppertop dept.

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."

    I think this is something that only Power Users will notice. It's not something important for the common user.

      I think a lot of people would notice if their laptop suddenly got a third less battery life.

      Excuse me sir, I believe your pun detector is broken.

      He might not have the capacity to appreciate such humor.

    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?
