[Bug 557695] Re: Lenovo X100e hard-locks when a function key is pressed

[Alex Chekholko]

Actually, just double-checked, and the function keys for volume control
work.  The function keys for brightness hard-lock the machine.  The
"sleep" function key also works, but some of the others don't do
anything.

** Description changed:

  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.
