Subject: Re: ports/94894: multimedia/fxtv causes freeze and reboot on DGA failure on FreeBSD 6.1-PRERELEASES

I did a bit of debugging on this to see where the problem was. I went into
the multimedia/fxtv folder and told it to patch the source but not build it.
I then did 'gmake DEBUG=YES' to get a debugging version of fxtv. Using
this, I managed to find out where fxtv was freezing up my system. The
output from gdb is below. Aparently it's getting held up at the ioctl of
TVTUNER_SETCHNL. I'm not sure if that means it's a bktr issue or a fxtv
issue, because I also installed xawtv and kbtv, and of those, xawtv can play
the audio but not the video (although it does show something if I turn off
overlay, but it never changes), and kbtv (using mplayer as it's base) can
only show a messed up picture and plays the audio. If it is a bktr issue,
which list would be the correct one to submit the problem report to? In any
case, since I haven't been able to view TV properly with my card and am only
using it to play on my GameCube using the video inputs, I edited the source
to bypass that ioctl and a later function that was killing it. It now runs
fine for video input. But since that won't help anyone wanting to watch TV,
I don't have a patch. Just in case, here's the dmesg clip for my tuner:
