This one is another instance of the APIC error in the XCP boot that
causes the SCSI driver not to come online.

This one I can't see anything wrong.  The host boots fine, but then
the ssh to start the localmigrate command just fails.  Nothing on the
serial console to indicate what might be wrong.

This one looks a bit like the above, but the ssh failure happens on
the 3rd iteration; and there are all kidns of scary messages from the
blk subsystem:

Looks like either a transient bug in the driver, or hardware that's acting up.

NB that all of these failures happened on potato-beetle; not sure if
that has any significance.
