I yanked out my adaptec scsi and the unused miro cards and my
PVR-350 has not hung since. Now to try and get it to work with
the scsi card installed, since tape drives are a good thing :-)

I did get another panic,

I had rebooted my system yesterday (back to 5.2 to get some work
done and then back to 4.9 to play with the pvr-350 some more). I
had decided to give the freevo port a go and started by running
portupgrade overnight. Today I tried to load the cxm modules and
it paniced. I was in X at the time so I didn't see the kernel
messages, but this is what made it into /var/log/messages:

and a backtrace looks like:

When I rebooted the computer, I loaded the modules without a problem.
