[Bug 524281] Re: Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled

[Michele Di Maio]

My results for the "power" kernel:

Wakeups-from-idle per second : 249.2	interval: 300.0s
no ACPI power usage estimate available
Top causes for wakeups:
  29.7% ( 72.9)   [kernel scheduler] Load balancing tick
  14.2% ( 34.9)   docky
   8.6% ( 21.0)   [extra timer interrupt]
   8.1% ( 19.9)   desktopcouch-se
   6.3% ( 15.5)   [ata_piix] <interrupt>
   5.6% ( 13.8)   [iwlagn] <interrupt>
   4.9% ( 12.1)   [kernel core] usb_hcd_poll_rh_status (rh_timer_func)

And for the "unpatched":

Wakeups-from-idle per second : 228.8	interval: 300.0s
no ACPI power usage estimate available
Top causes for wakeups:
  31.7% ( 85.6)   [kernel scheduler] Load balancing tick
  12.9% ( 34.9)   docky
   9.1% ( 24.5)   [extra timer interrupt]
   7.4% ( 19.9)   desktopcouch-se
   5.8% ( 15.5)   [ata_piix] <interrupt>
   5.0% ( 13.4)   [iwlagn] <interrupt>
   4.5% ( 12.1)   [kernel core] usb_hcd_poll_rh_status (rh_timer_func)
