Description christian 2008-07-06 23:59:57 UTC 
Version:            (using Devel)
Installed from:    Compiled sources

Top causes for wakeups:
  20,7% (138,7)       <interrupt> : uhci_hcd:usb4, ehci_hcd:usb8, wifi0
  16,1% (108,3)       <interrupt> : uhci_hcd:usb1, libata, nvidia
  12,3% ( 82,3)          knotify4 : schedule_timeout (process_timeout)
  10,7% ( 72,0)      <kernel IPI> : Rescheduling interrupts
  10,1% ( 68,0)      npviewer.bin : schedule_timeout (process_timeout)
   7,3% ( 49,0)      npviewer.bin : futex_wait (hrtimer_wakeup)
   7,0% ( 46,7)       <interrupt> : HDA Intel
   4,0% ( 26,7)            kopete : schedule_timeout (process_timeout)
   2,0% ( 13,7)             skype : schedule_timeout (process_timeout)

see the wakeups from programm powertop, knotify wakes up the CPU too often ?
