I've had a look in /proc/pci and the raid controller is indeed
sharing interrupts with the onboard network controller and the
onboard usb. I can't find anywhere in the bios to change the
assigned IRQs, or disable the internal devices. Any suggestions
on how I might do this ? (I've just flashed to the latest BIOS
version and that doesn't help)

I tried removing the ide0 and ide1 entries, but that doesn't seem to
change anything (kernel still panics). I notice that you specify the
IRQ number in your append line. Is this necessary/good or not?
Also, newbie question, I'd like to send the output of from the kernel
before it panics to the list. How do I capture the text?

Thanks! And thanks for your help :-)
