nice catch, but... mythic ~ # ls -al /dev/video* lrwxrwxrwx 1 root root 10 Feb 21 17:10 /dev/video0 -> v4l/video0 lrwxrwxrwx 1 root root 11 Feb 21 17:10 /dev/video24 -> v4l/video24 lrwxrwxrwx 1 root root 11 Feb 21 17:10 /dev/video32 -> v4l/video32 digging more into the problem is seems to be the old DMA issue. using cpufreq with an amd64 architecture causes ivtv to freak when the cpu changes frequencies. if i compile a kernel without cpufreq drivers it seems to work without issue. sucks because now i have to listen to the cpu fan running 100% all the time, but at least i know why... _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
