Sound class oops

Sound class oops

[@ 2003-12-15 6:11 UTC (permalink / raw)]

Hi,

I applied the sound class patches (ChangeSet@1.1817.1.712 and
ChangeSet@1.1817.1.713 at linuxusb.bkbits.net/usb-2.5) to plain
2.6.0-test11, and noticed that it started oopsing when reloading the
ALSA drivers (after an initial successful load/unload). On plain -test11
reloading the modules works fine.

The modules loaded (by the Debian ALSA init script) are:

% lsmod | egrep 's(ou)?nd'
snd_maestro3           21508  0 
snd_ac97_codec         52452  1 snd_maestro3
snd_pcm                88036  1 snd_maestro3
snd_page_alloc          9092  1 snd_pcm
snd_timer              21412  1 snd_pcm
snd                    44292  5 snd_mixer_oss,snd_maestro3,snd_ac97_codec,snd_pcm,snd_timer
soundcore               8224  3 snd_pcm,snd

Here's the oops output:

Yeah, I'm getting odd oopses too.  I'll be working on fixing up the
sound class patches next week.  Sorry about this.
