Hi Folks,
I recently bought a PVR-500 to replace my existing low-quality
saa7139 card. I've finally gotten through the various
instructions and have gotten nice high-quality video out of
/dev/video0.... but only for about 5 seconds, after which my
machine reboots!!! There was a previous thread on the list where
someone complained of having problems with KT133 motherboards, and
since my mobo (Soyo KT400) uses the KT400 chipset, I thought there
might be a problem.
It's a fairly common problem, most VIA-based boards won't even boot
with PVR-500. It's not strictly a chipset problem, at least one vendor
(ASUS) acknowleged the problem and released a BIOS update which fixes
it. As far as I know, Soyo did not, I could not get Soyo Dragon 2 to
boot with PVR-500.
Try the latest BIOS for your board, but if that does not work, you're
pretty much hosed.
Also, with the .3x release of ivtv, it seems that the
no_black_magic flag is no longer an option, as I get the following
in dmesg when I try to install the card:
cx25840: Unknown parameter `no_black_magic'
In any case: perfect video for a few seconds, then POOF reboot.

Older VIA Chipsets, especially the KT133, have rather... fragile... PCI
busses. The best known symptom is the cracking sound caused when using a
Sound Blaster, from the PCI bus flooding and choking.
I'd assume a PVR500 would throw a fair bit of data around the PCI bus...
