[Johannes Baumann <johannes.baumann@gmx.de>]

Hi,

i had serveral kernel panics in the last days on a DELL R300.
First i had ubuntu 8.10 running with latest kvm compiled.

Right now i have fedora 10 as host system running, with the newest kvm
version. My CPU is Intel(R) Xeon(R) CPU X3363  @ 2.83GHz Quadcore.
I have 2 Windows 2003 Enterprise Domains running at almost no load.
Im not sure when to panic happens but it think its reproducable if the
guest systems are under load.

What can i do to get more debug information?

Thx so far.. Johannes
