Hi
I am using a Pinnacle Dazzle DVC100 Rev 1.1 USB frame grabber card, and
each time I stop capturing video the driver crashes. This happens both in
an unpatched 2.6.37 kernel and in the debian 2.6.32-5 kernel.
The kernel says:
kernel BUG at drivers/media/video/em28xx/em28xx-video.c:891
[1.] One line summary of the problem:
em28xx driver crashes and usb subsystem hangs when video capturing stops.
[2.] Full description of the problem/report:
em28xx driver crashes and usb subsystem hangs when video capturing stops.
This always happens when using memory mapped kernel buffers.
[3.] Keywords (i.e., modules, networking, kernel):
usb video em28xx v4l2
[4.] Kernel version (from /proc/version):
Linux version 2.6.37-rst (rst@mate) (gcc version 4.4.5 (Debian 4.4.5-6) ) #1 SMP PREEMPT Wed Jan 12 21:28:37 CET 2011
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

[6.] A small shell script or example program which triggers the problem (if possible)
No shell script exists.
Start capturing video using memory mapped kernel buffers, then stop
capturing. Driver crashes immediately.

Hi
The crash is not as consistent as I first believed. I have managed to stop
and start capturing several (but not many) times without the driver
crashing now.
The trace logs also differ slightly. Here is the last one:

Hello Rune
I'm trying to learn more about the linux kernel so I figured helping
with bugs is a good way to get started.

To me it seems that the resource locking (functions res_get, res_check,
res_locked and res_free) is subject to race condition.
I looked at older versions of the code and found that there used to be
locks around some of these pieces. It was removed in commit:
0499a5aa777f8e56e46df362f0bb9d9d116186f9 - V4L/DVB: em28xx: remove BKL
Other V4L drivers use pretty much the same code (res_get, res_free,
etc.) for resource locking but still have the mutex_lock/unlock around
it. Does anyone know why this was removed?
Thanks

Because now the video4linux core does the locking.
Anyway, I'm pretty sure this is the bug that was fixed here:
http://www.mail-archive.com/linuxtv-commits@linuxtv.org/msg09413.html
This fix will be in 2.6.38.
The change in the locking mechanism had nothing to do this particular bug.
It was just incorrect administration of resources.

Thanks for the explanation. I see now how the V4L core locks around the
ioctls. The member unlocked_ioctl of struct v4l2_file_operations
confused me a little. Maybe serialized_ioctl would be a better name? Not
a big issue though.
Hopefully the patch fixes your problem Rune.
