[mythtv-users] Backend Crapping Out - Solved (I think)

[Debabrata Banerjee]

No matter what you do it will always be unstable, but maybe stable enough to
keep you happy. kt133* boards should be all thrown in a pile and set on
fire. Add 760mpx to that list too. I don't know how such crap PCI
implementations made it through QA.

Well I was just about to throw my MythTV machine out the window and at least
some enjoying watching it hit the pavement and shattering into a million
pieces when I made a decision.

I decided that I would try the Knoppix based MythTV install to see if maybe
there was something in the ATrpms that my stupid system didn't like.  I
mean, it wouldn't be the first time something I built didn't work or blew up
or made me so angry I wanted to light said thing on fire and watch it burn.
Anyways, I trolled around on the mysettopbox forums and was reading more
about the wonderful VIA chipsets.  I read, for a second time, all the things
I have already tried.  Then I read something I can't believe I didn't think
of: (this is a loose quote) "The only thing you can do is update the BIOS
and hope for the best."  Holy crap, I can't believe I didn't even think of
that.

So, when I got home from work I updated the ASUS A7V133 board to the latest
BIOS revision 1009.  Well as of right now, 7:49pm EST, my machine has been
playing TV since 4:00pm EST non stop.  And, it even recorded Charmed at
6:00pm while I was watching it!

So here's a checklist for troubleshooting the DMA problem associated with
VIA chipsets:

1. UPDATE THE BIOS!!!!!
2. Turn off APIC in the kernel and in the BIOS
3. Get your IRQ's in order, turn off everything you don't need in the BIOS.
Check IRQ's with dmesg and check the PCI addresses against the ones you'll
see in 'lspci -v' 4. Move the hard drive(s) you are using to an IDE
controller that is not on-board.

If that doesn't work take the board out of the machine and douse it in
gasoline.  Then, after you've lit the whole mess and you sitting there
watching it, start surfing eBay or froogle for a new board.

I'll keep you all informed if anything funky crops up.
