Comment 8 for bug 373245

Hello,

i am seeing the same behaviour, hrtimer_start_range_ns causes more than 2000 wakups:

  87.4% (2002.0) <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
   7.6% (174.2) <interrupt> : ahci
   1.3% ( 30.2) <interrupt> : iwlagn
   1.2% ( 27.2) <interrupt> : acpi
   0.7% ( 15.8) <kernel IPI> : Rescheduling interrupts
   0.6% ( 13.8) firefox : hrtimer_start_range_ns (hrtimer_wakeup)
   0.2% ( 5.4) thunderbird-bin : hrtimer_start_range_ns (hrtimer_wakeup)
   0.2% ( 3.8) plasma : hrtimer_start_range_ns (hrtimer_wakeup)
   0.1% ( 3.0) <interrupt> : i915

This happens with kernels 2.6.29.4 - 2.6.30-rc7-git1. If you need more Info, tell me, i am happy to provide if i can.
