I monitor as well knotify4 wakeups and it's always around 10% (100)

 29.3% (325.8)   USB device  3-2 : B2C2 Broadband Rcvr USB Adpt. (B2C2, Inc.)
  24.8% (275.7)       <interrupt> : ehci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb4
   8.9% ( 99.4)          knotify4 : schedule_timeout (process_timeout)
   7.8% ( 86.3)       <interrupt> : saa7133[0], saa7133[0], nvidia
   6.8% ( 76.0)              kwin : schedule_timeout (process_timeout)
   4.4% ( 48.5)           mplayer : do_nanosleep (hrtimer_wakeup)
   4.2% ( 46.9)       <interrupt> : snd_ca0106
   3.5% ( 38.4)           konsole : schedule_timeout (process_timeout)
   2.8% ( 30.7)   USB device  2-1 : Microsoft Wireless Desktop Receiver 3.1A (Microsft)
   1.2% ( 13.7)       <interrupt> : pata_via
   1.2% ( 13.0)       <interrupt> : pata_pdc2027x, ndiswrapper

The above results from powertop is with plasma not running. They do not change if i run plasma. I have only one plasmoid on desktop (folder view)
