(In reply to Andriy Gapon from comment #4)

can you also try kern.eventtimer.timer=HPET ?

(this seems to make the most difference, especially if you have LAPIC assigned
which I think is the default, and my guess is that it's pointing at the root
cause of the problem if changing the event timer helps as much as I think it
will)
