CPU0 FATAL TRAP 6 -> Not possible to run FC5 guest on kernel-xen0-2.6.16-1.2122_FC5smp

[Thomas von Steiger]

Hello,

I try to run FC5 guest on dom0 kernel-xen0-2.6.16-1.2122_FC5smp.
FC5 Guest boot's up without any problem only with single core kernel.
If I do something like "yum update" or bonnie++ on this guest I get always
the same "CPU0 FATAL TRAP 6".

On version kernel-xen0-2.6.16-1.2096_FC5 I can not start a FC5 guest ->
guest stops with boot up.
With kernel-xen0-2.6.16-1.2096_FC5 I can run rhel4, rh72 guests stable (not
smp).
