I've seen this, too. I can reproduce it with
call bcsf0 db0hsk # connect to someone
-- switch off trx -- # so no replys can be received
~. # disconnect - connection stays in DISC sent state
# waiting for DM
ifconfig bcsf0 down # oops following ....
The oops is usually not immediate but with an up to 4 second delay!

Homemade system(s) here. (Alpha and i486)
currently kernel 2.2.8, but I already noticed this some time ago.

Yes :-)
>From what I remember I found out from the trace that the oops happens
because there was a timer left over whose handler doesn't exist any more
when the device is down. Maybe the 'heartbeat' timer?
If there is demand for more detailed info I will investigate this again.
