[bostjan <bostjan@xxxxxx>]

By updating mba6x_bl module this issue went away.

I am unable to replicate it on 4.4.x as there are build issues (initial
is with stack protection gcc flag which does not yet exists in trusty,
then something about signing module).

Feel free to close this, as it gets resolved with module update.

Tnx for hints though,
b.

Title:
  Macbook Air 6.2 brightness buttons stopped working after 3.13.0-63

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Buttons for brightness do not work after resume if kernels fresher
  than 3.13.0-63 are used (I tested with -65 ... -68, don't know about
  -64).

  If I reboot it with kernel -63, everything is back to normal.

  Any hints about this one?
