------- Comment #44 from jamundso@xxxxxxxxx 2010-05-04 12:41 -------
I've seen this for forever on Dell PE2600 boxen running CentOS 5.x, and note
the hpet_force workaround seems completely ignored. Also, in my current
example, there are no domU's involved whatsoever - just the running dom0 is
enough...
