Regarding PR 48279. I cought an kernel trap. Usually it just freeze, and that's
it. I hope this could be helpfull.
It might be a pci lookup. But the behaviour on my system suggest initialisation
fault. As I can run fxtv for months without any hickups. The only catch is that
the very first thing one have to do is to start xfree86, and then fxtv
immediate after boot.
Another observation I did recently was that running ffmpeg right after boot
freeze the machine. But starting xfree86, and then fxtv. After that ffmpeg runs
without problems.
