No such luck here; I've just tried an amd64 machine (8-STABLE from
today) in a new installation of XenServer 5.6 and while the GENERIC
kernel works stable enough, the XENHVM kernel produces all kinds of
timer-related problems, accompanied by messages like:
Feb 18 23:20:03 xbsd kernel: calcru: runtime went backwards from
28669021884109 usec to 22622950 usec for pid 11 (idle)
The difference between 28669021884109 and 22622950 is huge! It almost
looks like a memory corruption.
