This is a new install- I'm running a PVR500 in a P3-667 box. The box was very stable in it's previous life, but I added the PVR500 and an nVidia 6200a AGP card to it recently. I have a DISH-500 box feeding SVideo in to the '500 on video0. No attempts to control the Dish box yet.

I can play MP3s, videos, etc, except when I hit watch TV, it reboots in 0-10 seconds. When I do get live TV to play for a few seconds, the audio is scratchy too.

Nothing in the logs prior to the reboot.

I followed the instructions here to install the newest ivtv driver (0.4.5) compatible with my core(Linux version: 2.6.15-chw-2).

Doing a "cat /dev/video0 > test.mpg" causes an immediate reboot.

The PCI latency was set to 32 in BIOS, I upped it to 64, then 128 with no effect (other than the warning message going away).
I upped the AGP memory hole from 32 to 256MB with no effect either.

Any ideas of what to try next?

When I run:
Code:
dmesg | grep -i irq | grep -i disabl

I got this:
Code:
ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 6 7 9 10 11 12 14 15) *0, disabled.
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled


So I went in to the BIOS and disabled COM2, and the LPT port to free up interrupts. No effect.

I pulled the sound card, and rebooted and it lasted much longer. I was getting some tearing on screen, and no audio of course.

I'm pulling cards, and playing with interrupts... so far I've forced the int. to 3 for the PCI slot the card is in, and it is stable for now... going to test more of course.

Then work on getting audio working again.

Well, that didn't last long. Looks like I get up to 5 minutes of viewing live TV, then a reboot.

I've pulled the NIC and sound card. The only card left in the machine other than the PVR500 is the AGP video.

I forced interrupts on that slot, to no real effect.

I'm out of ideas. :(

What chipset does your motherboard use? I'm guessing VIA, ALI or maybe S3?

It's a nForce2 chipset, with a new AGP 6200 card in it.

I gave up and bought/built a Dragon copy with the MSI board. The 500 works fine in that system, although I had to do a new install.

Did you try it without 0.4.5 first? I recommend that people avoid 0.4.5 at this point in time, because it has known issues.

Did you try the CompileIvtv instructions on the Wiki? With a vanilla install forcing the use of the 04.4 drivers by doing step 4 gets most recalitant PVR-150 and PVR-500's working.

I did try it with the stock R5C7 install first. After many hours of messing with the bios, I tried to update ivtv via the compile ivtv. I did just pull down the newest files though, so may have missed the combination that worked.

For my needs, I was just test-driving Myth on that box before I bought a new box. I proved to myself that it would fulfill my needs (when I got the record working), so went ahead and bought the new box.

Thanks a lot for your help though- I'd never even come close without this site to search/ask on.
