I'm suspecting that your HPET counter is being stopped for some reason, although why I have no idea.
Just to get a clear picture, does this happen w/ "Tickless System (Dynamic ticks)" disabled in the menuconfig?
Thomas, might we be actually stopping the HPET counter instead of disabling the HPET interrupt w/ dynticks?
