Linux Kernel Suffering Power Management Regression? 186

Posted by Soulskill on Friday April 22, 2011 @05:18PM
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.

It's open source. All the programmers will get together and exam the code and fix it! That's the power of open source - it's just like the million monkeys, you just have to keep waiting until the monkeys happen to get it right. Maybe this wouldn't be a problem if they weren't obsessed with changing the damn thing so frequently.

I lost the ability to hibernate my machines in the last few kernels, how about fixing that?
