I've run powertop and here's what it reports:

Wakeups-from-idle per second : 793,2    interval: 10,0s
no ACPI power usage estimate available

Top causes for wakeups:
   99,5% (3003,5)     <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
    0,2% (  5,0)                 X : run_timer_softirq (cursor_timer_handler)
    0,1% (  2,0)                 X : clocksource_watchdog (clocksource_watchdog)


Regards,
Alexander.
