Keith,I have had some success minimizing these kinds of problems on my SMP machine by tweaking my machine's IRQs. If any devices share your ivtv card's IRQ, remove / shuffle the cards until you have a good config where the card has its own IRQ.
Ricardo, was this on 64bit as well? Because it's looking to me like some 64bit bug was introduced after 0.6.1. If people on 64bit are only having trouble after this version but with 32bit are ok, then can this still be IRQ related? On my machine, ivtv0 and ivtv1 have their own, non-shared interrupts.
I never looked at the source before this evening, but it looks like ivtv_pause_encoder() was completely ripped out and replaced with some new api call ivtv_vapi(). Maybe that has somethig to do with it? I really have no idea. Something new has caused the firmware to go out to lunch though (or appear to be out to lunch), and only on dual core 64bit as far as I can tell.
Maybe I'll just punt and reinstall with FC5 32bit. I wonder how many people out there have had ivtv success with an athlon X2, and 64bit disto. Please let me know off-list. Thx.
