Comment 131 for bug 524281

Rocko,
Tried it and there wasn't a great deal of difference overall on my Thinkpad X300

The Load balancing ticks dropped some but
were replaced by a new item called kworker/0:0

Here is the result from powertop -d

Wakeups-from-idle per second : 226.3 interval: 15.0s
no ACPI power usage estimate available
Top causes for wakeups:
  20.0% ( 28.1) kworker/0:0
  13.5% ( 19.0) [kernel scheduler] Load balancing tick
  13.0% ( 18.3) firefox-bin
  12.4% ( 17.4) [extra timer interrupt]
   7.1% ( 10.0) nautilus
   5.4% ( 7.6) [iwlagn] <interrupt>
   3.5% ( 4.9) syndaemon
   3.2% ( 4.5) [TLB shootdowns] <kernel IPI>
   3.2% ( 4.5) [kernel core] hrtimer_start (tick_sched_timer)
   2.9% ( 4.1) apt-check
   2.5% ( 3.5) [acpi] <interrupt>
   2.1% ( 3.0) Xorg
