 My Dual800 ran fine for well over a week in my office with 1GB of RAM and
with SMP. It also ran with a load average of around 10 for a couple of
hours when I tried to stress test it. It was only when it started getting
a bit of network traffic after moving it into our machine room did it
crash, and then it crashed often. (It was also compiled with GMAC and BMAC
network drivers).

 So, don't know if this info helps or not, but I'd say try giving it a
network stress test as well as a heavy CPU load. Once I turned off SMP, it
seems to be very stable (still with 1 GB of RAM).

Cheers,

Chris
