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

[Flávio Etrusco]

Funny how the comments in the Debian tracker suggests says "worksforme" and suggests powertop is outdated without any data.
Latest powertop here lists this:

Top causes for wakeups:
  44,1% (199,2)     <kernel core> : hrtimer_start_range_ns (tick_sched_timer) 
  26,5% (119,6)       firefox-bin : hrtimer_start_range_ns (hrtimer_wakeup) 
  12,0% ( 54,2)       <interrupt> : extra timer interrupt 
   7,8% ( 35,2)       <interrupt> : ath, HDA Intel 
   1,8% (  8,0)     <kernel core> : usb_hcd_poll_rh_status (rh_timer_func)
   1,3% (  6,0)       <interrupt> : ata_piix, ata_piix, uhci_hcd:usb5, uhci_hcd:
usb7 Segmentation fault (core dumped)

And yes, it coredumps.
