This should not be possible, but I can crash my system with no effort.
The only thing I get logged is:

Jun 15 16:02:48 server kernel: Fatal double fault

All I have to do is run a program that seg faults or has some other
problem.  The most recent one was abiword.  I did the following:

gdb `which abiword`
(gdb) r

then I opened a file and did a "save as...", which causes a seg fault.
Then I did a

(gdb) c

and boom! reboot.
