Comment 11 for bug 260251

Ok. Since I didn't have much luck with the patch against the current Ubuntu package I've grabbed the latest version from Subversion and built that (Using the cmake/make combination). Unfortunately while programs no longer terminate with the 'VIDIOC_DQBUF error 5, Input/output error' they'll quickly get stuck in a EAGAIN loop (usually after 2 or 3 EIO errors). Again it seems to be very closely correlated with the 'bttv0: timeout' in the kernel log, though I can't seem to reproduce this error with any other program that uses v4l2.

I've opened up another bug on the OpenCV bugtracker and hopefully we might be able to work out what on earth is going on.
