No, the bug reports are really just for corner cases and there are no huge issues. However, both Linux and Windows give the HPET a relatively high priority that it probably does not deserve. :) For Linux you should be using kvmclock already, and for Windows the Hyper-V paravirtualized clock. If you don't have the Hyper-V pv clock, the RTC periodic timer is more battle-tested as an emulated clock/timer device; disabling the HPET ensures that Windows uses the RTC. Paolo
