Hi,
when I start capturing from the UVC-webcam 2232:1005 ("WebCam
SCB-0385N") of my netbook, I get a kernel panic.
You can find a screenshot of the backtrace here:

This is a regression which has been introduced between kernel 3.2-rc2
and 3.2-rc3 with the following commit:
3afedb95858bcc117b207a7c0a6767fe891bdfe9 is the first bad commit
commit 3afedb95858bcc117b207a7c0a6767fe891bdfe9
Author: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Thu Nov 3 07:24:34 2011 -0300
[media] uvcvideo: Don't skip erroneous payloads
Instead of skipping the payload completely, which would make the
resulting image corrupted anyway, store the payload normally and mark
the buffer as erroneous. If the no_drop module parameter is set to 1 the
buffer will then be passed to userspace, and tt will then be up to the
application to decide what to do with the buffer.

I'm puzzled. Your screenshot shows the uvc_video_stats_decode() function in
the stack trace, but that function wasn't present in
3afedb95858bcc117b207a7c0a6767fe891bdfe9. Could you please send me a stack
trace corresponding to 3afedb95858bcc117b207a7c0a6767fe891bdfe9 ?
Your stack trace looks similar to the problem reported in
https://bugzilla.redhat.com/show_bug.cgi?id=836742.
3afedb95858bcc117b207a7c0a6767fe891bdfe9 might have introduced a different
bug, possibly fixed in a later commit.

Hmm... you're right.
The screenshot I've sent to you was made during the bisection process at
a commit somewhere between 3.2-rc7 and 3.2-rc8.
It seems that this one is slightly different from the others.
This one is made at commit 3afedb95858bcc117b207a7c0a6767fe891bdfe9 (the
first bad commit):
http://imageshack.us/photo/my-images/811/img130hv.jpg
and this one is made at 3.5.rc6+:

Thank you Laurent, I can confirm that this patch fixes the bug !
Don't forget to add CC-stable (and a comment that this should be applied
to all kernels >=3.2 ?).
