Bug Description
Pressing one of the function keys hard-locks the laptop, requiring a cold reset. E.g. trying to adjust brightness or sound.
There is nothing at all in the logs after reboot; the machine just plain locks up.

It also hard-locks if you switch to battery power. Bug 535653 is probably a duplicate of this one. As far as I can tell, this bug doesn't have anything to do with Xorg.
