I built with debugging symbols, and this seems to be an issue with SCSI
disk emulation.  The traceback is:

and no progress ever seems to be made (the same address is read over an=
d
over)

I'm trying again with IDE instead of SCSI disks.  But I would like to
help debug the SCSI emulation... will look at it further later, and I'm
happy to provide any info someone else could use.
