[ 286.547348] BUG: unable to handle kernel paging request at 6b6b6b6b

["Justin P. Mattock" <justinmattock@gmail.com>]

With pulling git today I'm unable to shut the machine down completely.
(the system just sits there with the message on the screen);

* will now halt

Segmentation fault

after this message appears, if I hold down the start button
the system shuts off after a few seconds.
(BTW hopefully the number are correct,
manually writing this down, is a bit of a pain);
