[alsa-devel] Invalid PCM pointer with CMI8738 and pcm.c buffer underuns

[Andoru]

Okay, nevermind, the OS froze as I've tried to change the level on the PCM
channel, so I rebooted and tried to look for anything that might have left a
trace for what has happened, and I think I found what you were looking for:

It was under /var/log/messages.0 (same things also under /var/log/syslog for
some weird reason)
I haven't been able to see what caused the freezing.

Also found this, not sure if it's useful:
