I learned something new today.
It's a trick with "Alt+SysRq" you can do to an unresponsive
Linux-based machine (ctrl-alt-backspace not working)
Alt-SysRq-R (Puts keyboard in raw mode so kernel can receive commands)
Alt-SysRq-S (Puts the hard drive in sync)
Alt-SysRq-E (Stops all running processes)
Alt-SysRq-I (Kills all remaining processes)
Alt-SysRq-U (Unmounts the file system and mounts it in read-only mode)
Alt-SysRq-B (Reboots the system)
I always knew it as REISUB - I think that actually makes more sense
since you sync the drives after stopping processes and just before
unmounting drives.
It is a cool trick, I have used it more than once.
