similar bug
https://bugzilla.kernel.org/show_bug.cgi?id=29842
It could be related to this regression.

dedicate a couple release cycles to power management
I seriously believe that Linus should consider dedicating a couple of kernel release cycles to power management alone. Almost entirely accept only patches that tackle directly or indirectly power consumption issues, on all fronts. Make it also fun, with a 'Love mother Earth' or such tag line/theme. And what a better time to do so that this year, celebrating 20 years of Linux!
It is equally important for distributions to focus on power as well. I think Fedora is now making an active move in that directions with power-test liveCDs and such.

Maybe this is really a real problem...
Whoa!
After doing a very basic test in my working laptop with powertop, I found I'm having significantly more wakeups-from-idle per second with 2.6.38 (about 230) than with 2.6.35 (about 170). This means my CPU is waking up from idle more 26% than before! It's a significant difference...
I did my test only with my computer booted in OpenBox (without any programs loaded).
Btw, my laptop doesn't seem hotter with 2.6.38 than with 2.6.35, but more wakeups-from-idle per second means my CPU is spending more power...
Cheers
p.s.: I hope the kernel devs fix this problem in 2.6.39...
