Ah. I see now that the kernel panic was caused by the artsd process.

At least you've got it narrowed down to the pcm device.

I saw usb audio (uaudio0) in the dmesg. That's why I mentioned it. See:

uaudio_add_selector: NOT IMPLEMENTED
uaudio0: ignored input endpoint of type adaptive
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0

Doesn't look like it's getting installed/setup properly. But unfortunately,
I don't know how to fix it. Perhaps search google for usb audio troubleshooting
or something. Or identify the audio chipset and search google to see if anyone
else has gotten it working.

Sorry I couldn't be of more help.
