This could be the problem - ivtv and sound card sharing same IRQ.
Move that ivtv card to another slot, and see if you can get it its
own IRQ.

Does recording from applications other than MythTV cause your
system to crash?
dd if=/dev/video0 of=bla.mpg
I have tried adjusting PCI latency with no luck. I am booting
with no apic and CPU speed is disabled. What else can i try?
Do you have any IRQ conflicts? Shuffling around your PCI cards can
help.
cat /proc/interrupts
I believe this is a problem not with ivtv, but with MythTV:
database writes are done in the same thread as everything else, and
for whatever reason MythTV has too much to do, so it stops reading
the stream. Someone came up with a patch to spawn off separate
threads while recording, which, by and large, fixed these very
errors for many people. It's already in the MythTV SVN trunk, but
you can apply the patches yourself to 0.20-fixes (see the ticket's
asyncdb.2.patch):
http://cvs.mythtv.org/trac/ticket/1660
Some preliminary googling revealed that database errors in MythTV
can cause this too, so do some mysqlcheck -r / myisamcheck -r
whichever your tables are.

I suggest searching through the list for a thread with this title:
"Please test: loads of fixes, include DMA timouts (hopefully)" and
try the version at the link there. That should be the latest &
greatest
version with all the recent fixes in it. Hopefully that will fix
your
problem. If not, you could try searching the list or the FAQs.
There
are other things you can try - disabling cpuspeed, adjusting PCI
latencies, , nosmap, noapic, etc., etc., etc.
