I just had a large terminal server system (using RocketPorts) lockup.
Nothing was logged, keyboard was dead, but I did manage to hand copy one
screen full of data. I then combined the system.map and module load maps
and ran it through ksymoops.

I don't know how many GP's came before this, so I don't know how
meaningful this will be.
