   I seem to be hitting the BUG below with increasing regularity lately.
Typically it occurs right when a domU is in the middle of rebooting (it
appears to have shut down completely, I get a dom0 console prompt, then
the BUG below).  It's random enough that I haven't been able to isolate
it to a particular changeset.  Has anyone else seen this or (better yet)
have a fix?  It's getting in the way of testing all the new patches
since I'm seeing this on xen-ia64-unstable.hg.  Thanks,

        Alex
