Hello Yunhong, I was allready afraid it was only revealed by that changeset, 60 cpu's for free seems to good to be true :( Hope you can find it soon, it crashes the hypervisor frequently and fast (often right after boot). At least I didn't buy my null-modem cable and setup a serial console for nothing :-) Thx, -- Sander Tuesday, November 24, 2009, 10:38:24 AM, you wrote: > Have a quick look on the code, > This should be caused by following code in hpet_broadcast_init().
