Comment 63 for bug 276476

I have a machine running two guests under kvm, the first guest was upgraded to lucid just after release and has never shown an issue. However, just recently I upgraded the other guest and the host to lucid and now the recently upgraded guest locks up completely with a similar log to the ones above on a daily basis. When it hits this problem, network connections are lost and I am unable to shutdown normally. Sometimes I can issue a virsh shutdown and the guest will start to shut down, but then freeze. I have never been able to recover from this or escape from it ultimately any other way than issuing a virsh destroy and then bringing the guest back up.
