Angry NF-M2 nView / FC6 / Mythtv / Crash

I have an Abit NF-M2 nView motherboard (got it a few month ago). I've been trying to run FC6 / Mythtv on it. (Athlon64 Dual Core processor running 32 bit kernel, PVR-500, nothing else installed except on-board peripherals)

Here is what happens:

Installation of FC6 went fine, except that I keep getting MP-BIOS Bug, Timer not connected to APIC message

I did search through the forums and have used vairous combinations of acpi_skip_timer_override, acpi_use_timer_override, pci=nommconfig, acpi=off
The system will not boot with nosmp

No matter what I do, the result is the same - machine runs ok for a few hours and at some point at night it hangs. I have some shows scheduled to be recoded at night, so it looks like hangs in the middle of recording a show. In the morning, after reboot, there is a file with an unfinished recording. When the machine hangs, its a hard lock. When I look at the screen, I still see mythtv main screen, but the system in unresponsive. I even tried to recompile the kernel with a "magic sysreq" key enabled. Still hangs, sysreq does nothing.

Another interesting symptom is that sometimes when I try to play music or watch live tv, there is not sounds. All I have to do is restart a playback or exit and re-enter live tv. I have also noticed that network performance, using the built in network card (forcedeth drivers) is very poor

I do have the latest NVIDIA drivers installed, graphics seems to run ok. When I look at /proc/interrupts everything seems to be in order (listing below, this is with pci=nommconfig acpi_use_timer_override, if I dont use the last option, timer interrupt type turns to XT-PIC):

Any help would be much appreciated ! I am completely out of ideas.
