Hello everyone,

I installed the Gentoo Linux with 3.2.12 kernel on a Thinkpad T420, and I
used powertop to find out whatever is reducing my battery life, and I found
out that "Rescheduling Interrupts" was always the top and often cost nearly
50%, I have try the methods on website [1], but it didn't make things
different. Is there any method I could try to reduce the "Rescheduling
Interrupts"? Or it is a kernel bug?

Thanks in advance for any help.

Geraint Yang.
