Hi Davide,

Thanks for the response!

I guess you're asking did I check that the NMI counts were rising (i.e. 
they weren't staying at zero) and the answer, unfortunately, is yes - 
they were increasing steadily.

I checked exactly as you suggested using "cat /proc/interrupts".

Then, I ran X up and "boom", that's all she wrote :(

Best wishes,

Dan.

Sorry Davide,

I forgot to mention that a UP 2.6-test9 works fine whilst an SMP version 
doesn't (unless I use "noapic")

2.4 in dual or UP seems rock-solid (bar one issue which may have been 
network card related).

Dan.
