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.

Hi
This bug was filed for a very old kernel or the bug is old itself
without resolution.
If you can reproduce it with
- the current version in unstable/testing
- the latest kernel from backports
please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Regards,
Salvatore
