Hi Michelle!

You might want to try enabling "Magic Alt-SysRq" in your kernel. This will
give you a couple of useful features you can use to recover from most
crashes - kill all processes, unmount disks, reboot, dump current status,
etc. Did you build your own kernel, or are you using a prebuilt one?

See if you have a file /proc/sys/kernel/sysrq - if you do, write a 1 to
it. Then read the documentation in the kernel source about the commands
you can use.
