I tried the SBC kernel, and it did the same thing as the ncr kernel, 
excep the message said "sbc0:2:0..." instead of "ncrscsi0:2:0...".

The cables are attached solid, and the active termination light is on on 
the drive, and it's the last device in the chain.

I had a major filesystem problem which is what started this all off. I 
had a crash into the debugger, complaining of an fs problem. Then I 
rebooted, and it made me run fsck, and fsck wanted to remove about 100 
files, including the kernel itself. I told it not to remvoe the files, 
but I let it fix everything else. It said I had to reboot, and rucn fsck 
again. So I did, and it didn't recognize the drive as a scsi device.

It does seem like we could be looking at a physical problem on the disk, 
but I'm not quite sure how an fsck could cause a scsi device to fail to 
be recognized. Also, it just really seems that since I can mount this 
device in the installer, I ought to be able to somehow get to it w/in 
netbsd. Then I could at least recover it onto another disk. The 
installer's capabilities are a little too weak to be recovering hundreds 
of files.
