I am posting this to both to the ivtv board and to the mythtv board so that if others are having the same problem they can see my work around.
Symptoms: My mythbox have been plague with the ivtv driver not responding after the mythbox had been up for less then 24 hours. If I go to watch live TV I would see the dread black screen. Mythfrontend would state that it could not connect to the mythbackend. The mythbackend was still running. At that point I could not watch previous recordings because the frontend would state unable to connect to backend. Rebooting was so common that when my 2 year old wanted to watch one of his shows, he was no longer bring me the remote but the keyboard... Log Entries: I start to try to determine why the myth box was so unstable. The first thing I notice was "dmesg:spurious 8259A interrupt: IRQ7." Well according to some searches that I did this was "normal", because it was relate to the printer port. The interesting thing was that I had my printer/parallel port disables. I then seen these entries: kernel: irq 7: nobody cared (try booting with the "irqpoll" option. pvr kernel: [<c013e0a0>] __report_bad_irq+0x2b/0x68 kernel: [<c013e169>] note_interrupt+0x73/0x96 kernel: [<c013d6cc>] __do_IRQ+0x1bd/0x249 Mar 11 06:37:33 pvr kernel: [<c0104e04>] do_IRQ+0x5e/0x7a kernel: ======================= kernel: [<c01035b2>] common_interrupt+0x1a/0x20 kernel: [<c010103b>] default_idle+0x23/0x29 kernel: [<c010108f>] cpu_idle+0x1f/0x34 kernel: [<c03a5665>] start_kernel+0x16b/0x16d kernel: handlers: kernel: [<de950b83>] (ivtv_irq_handler+0x0/0x5b6 ivtv]) kernel: Disabling IRQ #7 ************************************************** I also notice that when I did "lspci -v" that my pvr-250 was using IRQ 7 *** SOLUTION **** NOT GOOD TO DISABLE THE IRQ 7 ON THE PVR CARD... So I went in the BIOS->"PCI Settings" and set the IRQ specifically to 3 for my pvr 250 and IRQ 4 for my pvr-350. Conclusion: I have been up for 3 days without a reboot. My 2 year old is now starting bring me the remote once again. ;-) ** QUESTIONS *** Why was the kernel "disabling" the PVR card? Is IRQ 7 supposed to be only used by parallel port operations? __________________________________ Do you Yahoo!? Yahoo! Mail - You care about security. So do we. http://promotions.yahoo.com/new_mail
