Same issue now here:

Hi there!

I installed a new mainboard, switching from a VIA KT600 to a NForce2
(Asus A7N8X-XE) chipset, switching via_sata to nv_sata and so on.

I never experienced any problems watching TV with my AverMedia (bt878 /
mt352) since it first ran here on my machine.

I watched in the archives... The patch referred to at
http://www.linuxtv.org/pipermail/linux-dvb/2005-September/004481.html is
some kind of outdated for me. I tried it, but nothing else than failed
HUNKs.

After mainboard switch now I got this:
`dmesg`:
bt878(0): irq FBUS risc_pc=37a14050
bt878(0): irq FBUS risc_pc=37a14050
bt878(0): irq FBUS risc_pc=37a14050
... (a million time or so)
bt878(0): IRQ lockup, cleared int mask

`gxine` (as an example application):
input_dvb: ERROR: Trying to get lock...

TV is sometimes watchable for about 2 or 3 seconds.

My system:
Software/OS
Gentoo Linux
Nitro-Sources 2.6.14
GCC: i686-pc-linux-gnu-3.4.4

Hardware:
Mainboard: Asus A7N8X-XE
DVB-T: AverMedia 771
