Description of problem:
IBM T23 laptop, sound hardware described in /etc/sysconfig/hwconf as:
desc: "Intel Corp. 82801CA/CAM AC'97 Audio Controller"
Sound may work (through xmms) when machine is first booted, but then
stops after some period of time, bringing up it's generic 'couldn't
open audio' error dialog. No other applications are accessing the
sound devices (/dev/dsp, /dev/mixer). The 'snd' sound editing
application hangs when attempting to play any sound. Stack trace:
#0 0x004cf782 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2
#1 0x00732a55 in open64 () from /lib/tls/libpthread.so.0
#2 0x00000000 in ?? ()
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start and stop xmms until it reports the sound device is not
Actual Results: xmms reports "Couldn't Open Audio"
Expected Results: xmms should play tunes!
Which output plugin are you using?

So if this is a kernel problem, should I redirect this bug?
In /var/log/messages, I see:

Should I rebuild snd on FC3? I am still using the version I compiled
Note also in the message log there is:
Oct 19 06:40:32 gvc kernel: application mozilla-bin uses obsolete OSS
My Mozilla RPMs are all 1.7.3-12. How bad is it if something is
accessing sound via OSS? Is it 'unsafe'? And if so, is it a bug that
FC3 Mozilla is doing so?
This happened to me again, and on a hunch I shutdown Mozilla. My
other apps started working.
/sbin/fuser on /dev/dsp and /dev/mixer didn't show any processes
having these devices open so I don't know exactly what's cauing this.
I plan to wipe my machine and reload with the release candidate
because I've got other 'issues' possibly related to doing an upgrade
from RH9. After I've done that I'll report back if I find this

Problem was resolved following a complete reinstall of FC3.
