As a side note about the microcode. We have received the third version
of the microcode and have a program which produces the following:

trap type 8, code = d50ae10, pc = c000e572
panic: Segmentation fault
trap type 8, code = d50ae10, pc = c000e572
panic: Segmentation fault

And the machine dies.
The program is a hypercube simulator with multiple forks and is thus
rather hard to trace through. I have a couple of students working on
it in an effort to isolate the exact configuration that crashes the
machine. If we can get it to a small, reproducable example, I will
forward it for others to try.
