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)
