My initial guess is that there is some conflict with another PCI
device. Another option is that there is very little memory
available.

That's what I was thinking, but tuner 1 (according to lspci -vv:
http://stuff.mjk.org/myth/lspci-vv.txt) is on IRQ 7, which nothing
else is using.  Even when ivtv is loaded up, IRQ 3 (for tuner 2)
shows up in /proc/interrupts, but IRQ 7 does not (indicating it's
not in use?).

Other than IRQs, what other conflicts should I look for?

What is the output of 'cat /proc/iomem'? I think there is a conflict
with the I/O memory regions. (I couldn't remember where to find this
info, it turns out it can be read from /proc/iomem).

Here is the output.  As I said in my previous post, I've since added
an old PVR250, which has allowed both tuners to be recognized on the
PVR500.  As this /proc/iomem is different from when the card wasn't
loading, please let me know if you'd like me to try and re-create
those conditions and ship you a new /proc/iomem.  Of course, I'm ok
with not doing it too.  :)


Please try again without the PVR250. That's really the interesting case 
to look at, although it is nice to have this as a comparison.

Thanks,

Hans,

Sorry for the delay, it's been a busy last few weeks. Follows is /proc/iomem WITHOUT the PVR250. I also snapshotted new logs for pretty much everything else and posted them here (w/ 12.03.2005 dates): http://stuff.mjk.org/myth/

Hope this helps, thanks!
