Bug has happen without special activity.

Some time before we done vm-shutdown command for PV guest (completed
successfully). At the moment of the crash no VM was running (except dom0, of
course).

Host was master in Xen Cloud Platform (v 0.5) pool (two hosts, iscsi shared
storage).

After the crash we lost connectivity with ssh server (but server continue to
reply to ping). We solve problem by hardware reset.

We using following hardware configuration:
