You have a Nakamichi, too--doesn't it happen on yours?  I've seen
similar problems on mine, and I've had to power down the changer to
get it to listen to reason.  Stick it in the uucp queue, and I'll take
a look, though I don't promise to come up with an answer.

An allied question (and the reason for including -current in the
reply): I find that when I do, say, 'df /usr' as myself (grog), the
changer will go through all disks it has loaded before coming back
with the correct information.  This doesn't happen if I'm root.  Any
ideas before I go code-digging?
