           Product: Xen
           Version: unstable
          Platform: x86-64
        OS/Version: other
            Status: NEW

I was trying to copy a small file from DomU to an NFS share. Dom0 crashed at
that point; nothing else was running. I was able to recreate the problem upon
reboot. Here are the 1st and 2nd traces:
