Unfortunately, I've still got some major stability problems. I do have all the
expected channels (presumabably I'd have 62+ if I had cable). Sound and
hardware
decoding work. But The card refuses to work for more than a couple of hours
without choking.

I get a bunch of barf like this when it dies

=================

I've gone to a lot of trouble to simplify my hardware environment (disable
things, etc.) I've disabled my second CPU (yes it is an SMP box). I've been
trying to do some research before whining some more, but I don't think it can
be
said that I've got it "working" :-( 

FYI, my environment:

Dell Precision 420
Duel PIII 933Mhz (one currently disabled)
1GB ECC RAM
Intel PIIX4 Ultra 66 Chipset (1 disk, OS)
Ultra100 TX2 Chipset (3 disks, mythtv data. Currently only one disk in use)
Debian "Unstable"
2.4.27-1-386 Stock kernel package (Was 2.4.27-1-686-smp)
ivtv-0.2.0-pre2l
Just about every piece of on-board hardware disabled
SoundBlaster "Live" PCI sound card

If you have any ideas and/or debugging tips, I'm all ears. I'll gladly write
some docs dealing with all of this stuff when I get everything fixed, if
there's
any interest...

Thanks.
-Mike.
