[Bug 373245] Re: karmic: wakeups <kernel core> : hrtimer_start_range_ns (tick_sched_timer)

[afunix]

Dell Inspirion 1520, Core2 Duo. 
Kubuntu Karmic without ubuntuone, mono, couchdb, ...

Linux afbook 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC
2009 x86_64 GNU/Linux

Top causes for wakeups:
  21,0% ( 37,5)     <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
  13,3% ( 23,8)       <interrupt> : extra timer interrupt
  13,0% ( 23,2)    plasma-desktop : hrtimer_start_range_ns (hrtimer_wakeup)
   8,8% ( 15,7)         konqueror : hrtimer_start_range_ns (hrtimer_wakeup)
   5,7% ( 10,2)      <kernel IPI> : Rescheduling interrupts
   5,6% ( 10,0)       <interrupt> : b43, eth0
   5,6% ( 10,0)             skype : hrtimer_start_range_ns (hrtimer_wakeup)

There is also a lot of  "extra timer interrupt" wakeups. 
"tick_sched_timer" sometimes near 100 wakeups per second.
