Funny how the comments in the Debian tracker suggests says "worksforme" and suggests powertop is outdated without any data.
Latest powertop here lists this:

Top causes for wakeups:
  44,1% (199,2) <kernel core> : hrtimer_start_range_ns (tick_sched_timer)
  26,5% (119,6) firefox-bin : hrtimer_start_range_ns (hrtimer_wakeup)
  12,0% ( 54,2) <interrupt> : extra timer interrupt
   7,8% ( 35,2) <interrupt> : ath, HDA Intel
   1,8% ( 8,0) <kernel core> : usb_hcd_poll_rh_status (rh_timer_func)
   1,3% ( 6,0) <interrupt> : ata_piix, ata_piix, uhci_hcd:usb5, uhci_hcd:
usb7 Segmentation fault (core dumped)

And yes, it coredumps.
