I'm running kernel 2.4.22 and alsa-0.9.7c on a Dell laptop, the driver used is intel8x0.
At the time of suspend, if the snd-pcm-oss module is in use, then resume will cause X
server to crash and I get an oops in syslog. Suspend/resume has no problem when
snd-pcm-oss is not in use. I have tried 0.9.6, has the same problem.
Below is the decoded oops(using alsa-0.9.7c):

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?

Could anybody look into > this problem? i don't see any obvious bugs in the resume code, and i thought it worked fine once on my test machine. could you check at which funciton the oops occurs, e.g. simply by puttig debug printk at each entry point? according to ksymoops, it's in snd_intel8x0_resume() (i.e. intel8x0_resume()). this could be either in snd_intel8x0_chip_init() or snd_ac97_resume(). in the latter function, there is no sleep or no wakeup, so it's likely in the former one.
