I think the basic problem is that my motherboard is buggy (it's a VIA chipset, go figure) and I have to take care over what interrupts are assigned to what devices.
I've pretty much solved it now by:
- ensure that IRQs are not shared at least between devices that generate a lot of interrupts (ie capture cards, network card and gfx card). It's impossible to not have some shared but you can minimise the overlap by setting the IRQ numbers in the BIOS for each PCI slot. I've now only got sharing between the major cards and minor devices like the USB controller and sound card.
- turn off ACPI
In particular, I've not had a lockup since turning off ACPI.
