Had killed xpdf with xkill several times while trying to print before
this happened.


Version-Release number of selected component (if applicable):

kernel-2.4.18-18.7.x.athlon.rpm

How reproducible:

Not, so far.

Comment 1 Michael K. Johnson 2002-12-18 02:00:46 UTC

There might have been multiple processes writing to a print
file from "xkilled" xpdfs at the same time.

Comment 2 Michael K. Johnson 2002-12-18 02:02:33 UTC

Very shortly after the oops, the system crashed without writing
to disk, and rebooted itself.

I don't think so Michael:

> Oops: 0002
> Kernel 2.4.9-34
> CPU:    0

Comment 4 Michael K. Johnson 2002-12-19 01:00:27 UTC

Doh, I forgot that there was a new kernel installed in the meantime.
Sorry, was clearly not paying sufficient attention.  I've closed this
WORKSFORME, can always reopen...
