It LOOKS the same to me... I have tried to reproduce this OOPS unsuccessfully, but it seems to be happening for many other users.
I can't imagine why I am unable to reproduce it.
Hopefully Andrew will pull from Mauro's v4l-dvb.git for the new changesets before he releases the next -mm...
The sanity checking cleanups have already been pushed up there:
http://www.kernel.org/git/?p=linux/kernel/git/mchehab/v4l-dvb.git;a=commitdiff;h=9c2f8a385c0bc40bf1f96edac32cc648d3a052fc;hp=0c445baf0daee379295adea8478278c0719e9c35
You might notice a tragic flaw in the previous code... bttv_register_video was checking the return value on a void ... Maybe we'll get some better debug output after this patch gets out.
Cheers,
