Wow..it really crashed hard.

Try running gdb over a telnet connection. If you want to get really into
it, printout the source for penetrate and start setting breakpoints.
Narrow down what is actually happening and where (in the code) it locks
the system. Then, trace that back up the chain of command into the
xserver (possibly rebuild X with -g..damn that would take a long time!).
Because the Linux kernel is not known for causing system lockups, I
would use Norton Diagnostics or something to run a full memory check.
Personally, I can't reproduce your bug. I'm using kernel 2.2.7 and the
custom-compiled X server provided by nVidia. Penetrate runs quite nicely,
though I prefer xmatrix :-)
