This probably isn't anything to do with the scsi async scan (boot with
scsi_mod.scan=sync to eliminate the possibility).  It's probably a driver
failing to finish the scan.  Probably the reason for that is broken
interrupt routing.  But that's a lot of probables, so some investigation
with scsi_mod.scan=sync should be used to confirm the first hypothesis
before assigning the blame elsewhere.
