DS10 6.0 new install hangs mounting root from ufs:/dev/ad0a

[Steve Rikli]

Just finished an apparently uneventful install of 6.0 from CD
onto a DS10.

The system hw is all healthy AFAI can tell -- it was previously
running OFS1 okay.

The 6.0 install finshed and I rebooted -- last thing it ever
says on serial console is:

  ...
  Waiting 5 seconds for SCSI devices to settle
  Trying to mount root from ufs:/dev/ad0a


and then nothing.  No more <cr> or ^c or the like do anything.

I've included as much of the serial console output as I could
capture.  Suggestions/help/etc. very welcome.

Cheers,
sr.
