[pvrusb2] Kernel oops?

[Mike Isely]

Can you please post entries from your system log leading up to this?
Thanks.

Obviously the oops involved the driver, but it would be far more helpful
to see the circumstances as well.

If you can reproduce the crash at will and isolate the key actions that
lead to it, that would also be quite helpful.
