In my current setup, I'm unable to assign the IRQ away from the onboard video card. In fact, changing it in the BIOS also changes it on the PVR-350 as well. I guess the BIOS doesn't want the two cards on different IRQ's. Go figure. On the IRQ sharing hunch, I swapped my pvr-350 and ram into another machine. Since the hardware is different (different motherboard, cpu, etc) this isn't conclusive testing, but, the other system allowed the PVR-350 to have it's own IRQ, not sharing with anyone else and guess what, it works flawlessly. I think the newer ivtv-fb and/or ivtv X driver versions just don't like sharing IRQ's at all. As far as I'm concerned it's ivtv's fault, but maybe the PVR-350's don't play nice sharing IRQ's? Anyone else able to comment on this? I'd be interested in seeing Rick's dmesg ivtv section and see if he's sharing an IRQ with a video card or something else... -Kenneth
