I'm running kernel 2.4.22 and alsa-0.9.7c on a Dell laptop. I have problem on
suspend/resume when alsa modules loaded. I have done a few testings, below is my
findings:
If the snd-pcm-oss module is in use(by arts sound server) at the time of suspend,
kernel
oops upon resuming and X server crashes. It has no problem when snd-pcm-oss is not in
use(
released by arts). 0.9.6 has the same behavior. My sound card is on-board intel8x0.
I searched the mail archive and didn't find any similar cases. Could anybody look into
this problem?
Below is the decoded oops(on kernel 2.4.22 with alsa-0.9.7c loaded):
