Public bug reported:

CID: 201402-14663 Dell Latitude XFR 12

The wireless key does not work on this system.
Keypress event could be captured by showkey, but not the release event
(Therefore the wireless LED won't change its color) 
 
Steps:
1, Install 14.04 + update (3.13.0-30), boot to desktop
2. Try to disable the wireless network / Bluetooth by pressing the wireless key

Expected result:
* Wireless network / Bluetooth should be disabled.

Actual result:
* Nothing happened

Debugging information:
ubuntu@201402-14663:~$ sudo showkey -k
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  28 release
keycode 240 press
keycode 240 press
keycode 240 press
^Ccaught signal 2, cleaning up...

xev cannot detect any wireless key event
