Others have addressed this, but let me add that there's a "Magic
SysRequest" key (or something similar) that can help you regain control
in some situations like this. I've never used it (nor studied up on it),
but thought I'd mention it in case you want to pursue it. It's an option
when you compile your own kernel.
Alt+SysRq+S - Sync Disks.
Alt+SysRq+U - Remount filesystems read-only.
Alt+SysRq+B - Reboot the machine (effectively a warm reboot).
Where is this SysRq-Key?
