I wish I could tell you what I was doing at the time when the oops was
generated. I noticed it the same night as it happened, but I can't narrow
it down much more. That night I was working on getting my dual pentium
(the one where the oops occurred) to process postscript files with gs and
send the output to a slower computer to send to it's printer.
The local printer was off the entire time so it would have shown up in the
logs had I printed there. So the only "printing" that would have taken
place was over the network with lpd.
It was late and I was tired at the time. I had also been fiddling around
with it long enough that I wouldn't beable to show the printcap files at
the time of the oops. I think I noticed the oopses when I saw the printer
remote spool entries pilling up. For a while I figured they were stuck in
a loop because of impropper configuration with the printcap, so I would
just lprm the jobs re-configure and try it again. I tried to strace -p
(the child lpd process) and it wouldn't let me. I think it was around
there I noticed the oopses. I kill -9'ed the lpd process, which worked,
and figured out how to get the printer configuration setup.
I included the original oops, and output of ksymoops and also the .config
for the system. I am running the kernel compiled for dual. I do not have
support for quota.
These is the current configuration dealing with the remote printer I was
print to. At one point in time I had one or both of the :lp=/dev/null:
lines set as :lp=: but I don't know how they looked at the time of the
oops. Those were the only two oopes produced at the time and I haven't any
oopes since.
