On my myth box I have a simple script that checks messages every 10sec and reboots if the usb disconnect line appears, I collect timestamped copies of the messages files.
A distinct pattern i still to occur, but some channels are worse than others, but that might be time of day caused reception variations.
Starting recording 3min ahead gives the box time to reboot and resume recording.

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.
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.
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:
Thanks,
- 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.
