Subjectkernel oops: test12-pre7, xmms, emu10k
Greetings,

2.4.0-test12-preXX has been pretty stable here on
a K6/2-450 running ipchains and various net services
in addition to workstation use.

I went to bed last night while others were listening to
xmms on my workstation while working in the room.

This morning I found that xmms was frozen, and there
were several oopsen in the logs.

After restarting X, everything is functional, and xmms
is working again -

I dimly perceive that xmms and the emu10k sound
driver seem to be involved, perhaps someone more
astute can see something more definite?

Here are the decoded oops:

ksymoops 2.3.4 on i586 2.4.0-test12-pre7. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test12-pre7/ (default)
-m /boot/System.map (specified)
