I don't know if this will help at all, but I've run into similar problems
on some systems that have AIC7870 controllers embedded on the motherboard
with *no* SEEPROM. It appears as though SCSI bus disconnect is not being
set - writes to the disk while the tape drive is busy guarantees a panic.
I've experienced this with both 2.1.0 and 2.1.5 - not tried it with 2.1.7.1
yet. The only workaround I was able to do was to install an AHA2742 and
stick all my devices on that. If you want me to recreate the crash and
provide info on it, lemme know. Can do. Not a problem. :)
Regards,
Sean.
