I think this is related to:
Clocksource tsc unstable (delta = -25767719801 ns)
Switching to clocksource hpet
On this AMD cpu that has a constant_tsc flag - seems to happen after 24 hours
or so, then the interrupts keep increasing.
So it looks like it's related to this:

(I don't know if there is a bug entry for it)
