kernel oops playing sound -- sound now wedged

[Carl Fink]

I used gmplayer (from Christian Marillat's excellent archive) to play a
video file this morning. Gmplayer froze, and I had to kill it. Now *no*
sound will play, and this is in /var/log/messages:

And now, I can't unload the sound drivers. They all report being busy. I'm
going to have to reboot to get sound back, I guess.

I've never experienced a kernel oops on this system. It's disturbing.

Should I report this as a bug in kernel-image-2.4.20-3-k7? There are
currently no visible bugs against any of the 2.4.20 kernels that I could
find. Or is it a bug in the sound modules?

And: I sent essentially this message about 6 hours ago, and it was never
posted. That's three messages sent to debian-user that just disappeared
into the ether, neither posted nor bounced. That should never happen. I
know lists.debian.org accepted them, because I'm running my own SMTP server.
Is anyone else experiencing this?

Sounds like time for "lsof" to see what is keeping the sound system
busy. Beyond that, while Christian Marillat does an excellent job both
on the packages of the archive he maintains and the many packages he
maintains in the Debian archives, mplayer (and its variants) is
something that I find requires a local build from source to *really*
work reliably on any computer I've worked with it. Download the source
from [url]http://www.mplayerhq.hu[/url], untar it and from its lead directory, run:

../configure --help | lpr

after which you can run debian/rules with the appropriate flags for the
type of system you have. It will work much better than what anyone else
can package because mplayer is still very machine specific.

Of course I rebooted days ago. I did use "lsof" but aside from reporting
that various sound modules used each other, it wasn't helpful.

As for compiling mplayer myself:

1. It shouldn't be relevant to a kernel oops, and

2. I've done so, and seen no performance difference between my package and
Christian's "k7" series.
