The extra wakeups are 'phantoms'.

Well I thought I was having better results after a reboot but that 
proved not to be true.  I just rebooted and I've got 22000 wakeups/sec.  
What's next?  I did get a message in dmesg that's interesting.  I'm not 
sure if this message shows up every time, maybe it's part of the problem.

from dmesg:

hpet_resources: 0xfed00000 is busy
