I have found out that certain mixes of kernel and ivtv drivers work well together. I have stuck with 2.6.18-1.2239 (fedora core 5) and ivtv 0.8.2-123 because of this. No spontaneous reboots ever with this system which runs 24/7 for months on end. I practically forget that I am watching LiveTV instead of regular tv. It happily supports 1 PVR500 and 2 PVR250's. Just for fun and also because supposedly it is the stable release and sheer curiosity, I compiled a
0.10.5 ivtv kmdl rpm and when I installed it, the system rebooted after a few minutes of recording or watching live tv, each time. So back to 0.8.2-123. It might not be the kernel, so I am glad I found an srpm of ivtv
0.8.2-123 from some old atrpms mirror, in case I need to upgrade the kernel. <br><br>From time to time though, I get <br>ivtv all encoder mpeg stream buffers are full. Dropping data<br><br>messages in dmesg. Very minor frame dropping which I can put up with.
