Dmesg output is attached (ivtv.log). 1) Interrupts are not shared. 2) No messages in the kernel log. The ivtv load messages are the last thing in the log after loading ivtv and letting it sit idle for quite awhile. 3) Captured the following from my kernel log (the only entries after loading ivtv once I did "ivtvctl -D 64"): Aug 28 11:32:38 gallifrey kernel: ivtv irq: ======= valid IRQ bits: 0x00000400 ====== Aug 28 11:33:09 gallifrey last message repeated 2013 times Aug 28 11:34:10 gallifrey last message repeated 3985 times 4) I attached two dumps of /proc/interrupts. The were captured approx. 1 minute apart. You can see how the interrupts (ERR and ivtv) increase. This is when I am NOT capturing but the driver is just loaded. New info just in: I just noticed that, if I do start capture, the interrupt ERRs in /proc/interrupts do not increase. When I stop capture they start increasing again. I was using MythTV watching live TV when I checked this. Hope this is enough info to get a start. Please let me know if there is anything else I can do or more info I can provide. BTW: if anyone else wants to chime in that they have this problem, please feel free. Thanks again Hans!!! -- Harry O.
