Bug#607114: Unresponsive Xen's dom0 system after 'general protection fault'
Package: linux-image-2.6-xen-amd64
Version: 2.6.26+17+lenny1
Severity: critical
Tags: lenny
After execution of xm create command I got messages in attached file.
I got this for second time within one week. Not sure what the root cause is.
Right now all of commands working with networking just hangs. Looks like
it has something to do with 8021q module.
All Xen domU's with NATed networks are reachable.
-- System Information:
Debian Release: 5.0.7

Peter Viskup
