The default Libranet kernel has a very nifty option available, named the "The magic SysRQ key". These are some keys that can be used to restart Linux safely when something bad happens. You can use a magic SysRQ key by pressing <alt> + <sysrq> + <key>. The following keys are available:
Key Function
r Regain control of the keyboard, this is especially handly for X keyboard hangs
k Kill everything on the current terminal
s Sync filesystems (writes away all cached changes)
u Remounts all filesystems read only
b Reboot the system
Especially the last three keys are handy in emergencies. Using "s", "u" and "b" in sequence will write away stuff (preventing data loss), bring the filesystems in a sane state before a reboot, and will finally reboot the system. Add an "r" before doing this sequence when your system locked in X.
This won't always work, but it can save the day on many occasions ;).
