Topic: Magic SysRq Key!

You guys may be familiar with REISUB, or something about raising elephants....
Anyways, even if your not... this is too useful to pass up:

http://en.wikipedia.org/wiki/Reisub

Essentially, the SysRq key gives some very low level and powerful functions that work even when your system is borked.
Probably the most well known, and the one i use before reading this is REISUB, which is a way to safely reboot without any damage to your system. (unRaw,tErminate,kIll,Sync.Unmount,reBoot)
This page is pretty neat, gives some background info, and has a handy chart of all the magic keys.

Re: Magic SysRq Key!

I was actually more interested in the other commands in the chart that aren't part of reisub.
