I am using VIA/AMD64 chipset with kernel 2.6.23.1 (the same system mentioned in my last posting about system instability). Based on a reply to my last post about system instability, I have disabled DMA in the ivtv driver. It is still to early to port a result regarding system hangs, but I am with DMA disabled still seeing a problem that preceeded the DMA change: the driver seems to "hang" on one of my two tuners, i.e. no video comes out of the tuner, yet the user program just displays a black image with no other indication of an error. The frequency of the failure seems to be directly related to system (i.e. disk I/O) load.
Attempts to reload ivtv (using modprobe -r or rmmod -f) fail. It seems that the only way to recover tuner function is a reboot. _______________________________________________ ivtv-users mailing list ivtv-users@ivtvdriver.org http://ivtvdriver.org/mailman/listinfo/ivtv-users
