I thought I had finally gotten this fixed with the kernel option

that seem to be related to high data throughput, but aren't consistent
enough for me to track down. When it freezes, only hitting the reset
or power button fixes it.
I have an MSI K7N2 Delta 2 motherboard with an AMD Barton 2500+ in
it. It has a nforce northbridge. I am passing the kernel "acpi=no
noapic nolapic". I'm running 2.6.11-6mdk. I have one PVR 150. I have
two hard drives, running LVM to make one video share. I'm running
ivtv 0.3.9
What happens is a hard lock up. It generally happens when I'm
exercising the ethernet hard.
This exact same thing was happening to me too with my KT6 Delta.

Can anyone give any advice on where to go from here?
Sure. The problem is almost certainly to do with interrupt sharing. In
my case it was a problem with the ACPI steering assigning too many
devices the same IRQ. I ended up fixing it by disabling unnecessary
onboard hardware (eg I don't need 8 USB controllers or onboard sound),
using acpi=off (is that different to your acpi=no ?) and re-positioning
the cards in the PCI slots. I would check your motherboard's manual
since some slots will share an interrupt whatever you do. You can also
assign specific slots a specific IRQ in the BIOS.
I've also heard that using SBLive cards can cause these sorts of issues
- and that's exactly what I am using. If I remove it and turn on ACPI
again it all works with no problems, but I need its SPDIF out. Ho hum.
Good luck.
