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:

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.

usb video em28xx v4l2
