Okay, so you also have phantom interrupts :). Although the thing is that when I
reboot (or start) the machine, its always in good state, and only after
sometime it goes into bad state.
I too get that hpet thing in dmesg : dmesg | grep hpet -
hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0
hpet0: 3 64-bit timers, 14318180 Hz
hpet_resources: 0xfed00000 is busy
Time: hpet clocksource has been installed.

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
