Bug report (involving ide and ide-cd)

[1.] One line summary of the problem:
A server was in production, then hung with an Oops. Seems to be to do
with ide-cd's IRQ's
[2.] Full description of the problem/report:
I left the server running cdparanoia, lifting wavs from a CD, while
running lame to convert a previous album to mp3, in a separate pts. I
had gone home. Others were also using the server for file serving,
proxying shell accounts etc. The server hung suddenly, console showed
an Oops. Server was completely non-responsive so the Oops was written
down by hand. I'm really not sure why this happened, but I guess it was
something to do with the CD (although lame wasn't using the CD so i'm
confused).
Server was totally unresponsive so other than the Oops on the console I
couldn't get any pertinent information. However the server was reset
and rebooted with an almost identical setup, except for apache which had
to be started by hand. All information below (except for the output
from ksymoops) was obtained from the current session (uptime 1 day, 1:21
hours since the oops at the time of writing this).
[3.] Keywords (i.e., modules, networking, kernel):
lame, kernel, ide-cd, ide, IRQ, lock
[4.] Kernel version (from /proc/version):
Linux version 2.4.18-3smp (bhcompile@daffy.perf.redhat.com) (gcc version
2.96 20000731 (Red Hat Linux 7.3 2.96-110)) #1 SMP Thu Apr 18 07:27:31

problem (if possible)
LAME version 3.92 (compiled locally)
[7.] Environment
All access to the server is via sshd, X was not running.
[7.1.] Software (add the output of the ver_linux script here)
If some fields are empty or look unusual you may have an old version.
