After some monkeying around, I'm suspecting the scsi controller on the MB as
having a problem.  I had a Seagate ST12400N disk, and swapped to the other
scsi interface in the system.  This brought about a reboot here...

rebooting

I switched to a Different ST12400N, but still had a problem.  Now it gets
past the boot, but panics at making the device files.

Now I tried a different disk all together, a DEC DSP3210S a faster disk
5400rpm.

Edit the fstab? [n]

Any ideas?  Do you think it's a hardware problem?

TIA!
