Did you by any chance do that from a terminal window in X11 environment? If that's the case, then kernel debugger is running, you just don't see anything because it can print stuff out only on console or serial port. If that indeed what happened, typing c and then ENTER should unhang your system. After that you can switch to the console with CTRL-ALT-F1 and enter debugger from there. --Artem
