Another shot worth would be:

https://patchwork.kernel.org/patch/2254211/

and

https://patchwork.kernel.org/patch/2254221/

If that doesn't help I suspect that the utter lack of locking for the backlight
code could be the culprit.

But the right course of action might be to revert both the above commit and the
original fix from Takashi (since oldest regressions win in this game here).
