Can you include some output from /var/log/messages before the oops itself? In my case I see USB disconnects, then an oops from something unrelated just after that.

You're right.  There's a USB disconnect before this occurs.   The messages are attached.   The same occurs with the other set oops's I've seen too.

Thanks,
Matt

This oops seems to be fairly regular.  I got another one today.  I see the USB disconnect again, but a slightly different stack.  See attached.

Some more info:

• From the timing of this oops, I know that Myth was just about to start recording with this tuner.
• My machine is a dual core AMD 3600+ AM2.
  

Thanks,
Matt
