Subject: Sound class oops
Date: Mon, 15 Dec 2003 06:11:57 +0000 [thread overview]
Message-ID: <marc-linux-hotplug-107146936926739@msgid-missing> (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:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:
