Unfortunately I have not received any replies on this, is there anyone who can help me? It doesn't have to be the solution, I'd be very happy with some tips on how to continue troubleshooting... Thanks!

There were a few replies, most regarding the ivtv version I was using (1.4.0). I have now upgraded to a newer kernel; tried both Gentoo's 2.6.30-gentoo-r4 and the vanilla 2.6.30.3 kernels and, unfortunately, the issue remains. At least I am now on 1.4.1: jer...@video ~ $ dmesg | grep ivtv | grep version ivtv: Start initialization, version 1.4.1 > I can easily reproduce the problem by running: > > dd if=/dev/video0 of=/dev/null bs=64k count=10000 > > usually it reboots before it reaches 5000 blocks, sometimes it takes a > little longer, but eventually the system reboots. > > I think that I rule out all other components of the system by copying to > /dev/null. I can still consistently trigger a reboot with this command. Any ideas?
