Hello all, I have a PVR-500 card on a Via Epia EN15000 board. I am running Gentoo Linux on it for MyhthTV. Ever since upgrading from kernel 2.6.22, I have been having reboots on my system whenever it tries recording something. Because I have had some issues with the SATA drivers on it previously, I have always suspected that to be the problem, however, after some more research I am now pretty sure that the IVTV driver is the culprit.
When using kernel 2.6.22 (with Gentoo patches) everything works fine. I have tried many different kernels after that, and with all the system eventually reboots. The current I have running is the vanilla 2.6.29.4 kernel, still the same problem. 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. Any video recorded with the card is good (that is, when it's not sent to /dev/null :-) ) I have checked http://www.ivtvdriver.org/index.php/Howto and everything seems to be installed as it should be, after that I checked http://www.ivtvdriver.org/index.php/Troubleshooting, but that does not seem to mention anything that is describing my situation. I have tried setting debug to 127, but I don't see anything that looks like an error, it also doesn't display anything just before crashing. the dmesg | tac ... etc script on the "how to ask for help" page does not give any output, so I'll just include dmesg | grep ivtv... I think I am using the in-kernel version of ivtv, but I am not 100% sure, how do I check? I have run out of options on what to try next, any ideas?
