[mythtv-users] Backend Crapping Out

[the Jer]

Ok here's a little update.
 
I did a card swap to get the PVR-250 on its own IRQ and I disabled everything I didn't need.  This still didn't help.
 
Also, upon further investigation I found that even though the mythbackend was still showing is a "ps aux" it actually was off in la-la land.  So I guess it still was dying contrary to what I said earlier.
 
So here's a quick summary:
 
1.  Everything works except watching Live TV
2.  Watching Live TV makes the mythbackend die randomly
3.  Simply restarting the backend make you able to watch TV again
 
It looks to me like the mythbackend is losing contact with the PVR-250.  I don't think the PVR-250 drivers (ivtv) are the problem because I don't have to remove and reinsert them to get things working.  All I need to do is restart the mythbackend.
 
I'm really stumped on all of this and quite frankly I'm about to put a boot through the machine.

HA!  More like dumb luck! :-D
 
Does anyone think a custom compiled system would mke htis work?  What I mean is, building a Gentoo machine for this and compiling it all myself instead of using the pre-built ATrpms?
 
Thanks for any help.

Jer,
        That's similar to the IRQ/DMA problem that I had with 2 capture
cards / 2 NICs.  I had to swap the NICs so that all the frontend
streaming traffic was not going out the one that caused the conflict.

        I've never really heard of a good way to eliminate IRQ
conflicts, but you might try eliminating any hardware on the system that
you don't need (USB, floppy, parallel port, etc.)  That'll let your
capture card get a different IRQ and may reduce the conflict.  I've also
moved cards into different PCI slots, and it eliminated lockups in
WinXP.

        The last AMD / VIA chipset machine I had suffered the window
fate for similar reasons (in the Win9X days)

        Setting up a Myth box seems to be more of an art than a science
;-)
