What I am attempting to do is add a tape drive to scbus1 at SCSI ID 4.
aic0 is an Adaptec 1510B PnP ISA card, which works fine as evidenced
above.
The problem is when I add the tape drive to the chain. The tape device is
internal, with termination on the end of the internal cable. The scanner
terminates the external segment. Termination on the card is disabled.
Once I plug the tape drive in, FreeBSD will not boot. NT and 98 both come
up fine, and recognize the tape drive. They both use the 4mm DAT device.
I ran a test backup under 98 just to make sure the drive is functioning
properly. The drive is a python archive (or maybe the other way around).
If I plug the drive in after boot, and attempt to rescan the SCSI bus
FreeBSD locks up, which isn't a huge surprise, since I can't quiesce the
bus before plugging in the tape drive. It was worth a shot.
From a cold or warm boot the kernel loads, and when it probes SCSI
devices, the machine locks up if the tape drive is plugged in.
Here's the config file from the machine in question:
