This time I did remember the "model=test" parameter. That crashed loading the OSS compatibility module

"cat /proc/asound/card0/codec#0" appears to have hung my command shell, and I think the desktop is going to crash soon. I can give the results under vanilla alsa-drivers if that helps. But first I want to post this before everything crashes
