Your instructions seemed clear enough, so I tried to reproduce your
problem. Now I have an ARM VM with a Debian installation that works just
fine and I have no idea what to use it for. ;-)

I also reviewed the patch that you mentioned and I can't find anything
suspicious there. I'm afraid you'll have to bite the bullet and run it
with some debugging code yourself (if it's really related to that patch,
you'll want to enable DPRINTF in hw/scsi-disk.c as a first step)
