Package: linux-image-3.2.0-4-amd64 Version: 3.2.51-1 Recording oopses sometimes after suspend/resume cycles within pvrusb2. This happens at start or few seconds into a recording started after such suspend/resume cycle.
Bisecting upstream tells me bd20948dc24c3a1cf5ea18385943783f11c2c751 is the first bad commit. (though it's not 100% because oops not always happens) This was touched again in 3.2.52, which I'm currently testing. No oopses happened as of this writing. I'll report back if something changes.
