(I sure didn't see it - did you send it to SCSI@freebsd.org?)
Posibly not a tape driver problem- this is where a disconnected command
timed out while disconnected. Justing could say ore accurately what these
messages mean.
Try turning on CAMDEBUG and do debug -Ic for this device - it'll fill up
your messages file, but at least we'll know what the last CDB active was
before things died.
I should note that I've seen this before on DLTs a lot- they seem to just
go completely out to lunch sometimes near EOT. I haven't had the time or
proper h/w to track it down (I have one 19th hand DLT4000 that was some
random Sun OEM'd model). Since I've spent > 5K$ on FreeBSD h/w not tied to
any paying project this year already, I'm not inclined to buy another tape
drive until at least January.
