md0: Preloaded image - system hangs on install

[Dan Harris]

Like the subject says.. I'm trying to install 5.2.1-RELEASE on a Compaq 
Proliant 6000 (dual Xeon, 1GB RAM, Compaq SCSI RAID).

When booting the CD: It gets to this message:

md0: Preloaded image (/boot/mfsroot) 4423680 bytes at 0xc09e16d8

at this point the system seems to hang with no recourse other than to 
restart.

The CD is known good (just installed fine on the box next to it, 
different hardware), and this box is currently running another OS 
without any problems.  Can anyone explain why this might fail and if I 
can do something about it?
