   It may  be fixed in a newer kernel...(referring to David's later comment)..

Just looked at it with powertop 1.10:


Wakeups-from-idle per second :  7.1     interval: 10.0s

Top causes for wakeups:
  42.9% (  6.0)           xfsaild : schedule_timeout (process_timeout)
  14.3% (  2.0)     <kernel core> : clocksource_register (clocksource_watchdog)
   8.6% (  1.2)           xfsbufd : schedule_timeout (process_timeout)
   7.1% (  1.0)                ip : tg3_open (tg3_timer)
