Comment 61 for bug 524281

Brian, the kernel from your PPA does indeed seem to help a little bit. I was getting an average of something like 140 wakes per second and now the average is around 100.

My computer still seems to spend a lot of time doing housekeeping... for example a recent powertop output:

 31,2% ( 78,4) [extra timer interrupt]
  21,1% ( 53,0) [kernel scheduler] Load balancing tick
  18,5% ( 46,4) [iwlagn] <interrupt>
   9,3% ( 23,5) firefox-bin
   4,0% ( 10,0) [kernel core] r600_audio_update_hdmi (r600_audio_update_hdmi)
   4,0% ( 10,0) ubuntuone-syncd
   3,7% ( 9,4) [kernel core] hrtimer_start (tick_sched_timer)

70 wakeups doing something I care about (wireless and Firefox) and 160 doing... other stuff.

Anyway thanks for the kernel, at least it's something until a fix gets backported officially! (Which I hope will happen, this being LTS and all.)
