I've been doing buildworld tests on an SMP build, 2-cpu 2550 w/ 2G of
ram configured. It gets through two or three builds and then crashes.
Unfortunately the crash seems to be completely undebuggable. It drops
into DDB> but the serial port is completely screwed up and I can't type.
Hitting <return> gives me colons and semicolons at db> prompt. Changing
baud rates does not seem to help.
This has occured twice. I am going to try dropping back to a standard
console to see if I can get better debugging. I don't know if this is
KSE related or not.
I've included the serial console output.
