Nikon D800 firmware upgrade, autofocus

I have noticed that after recent D800E firmware update to 1.11, auto-focus on two Sigma lenses (12-24 and 70-300) no longer works.

I would like to know two things:

1) Has anybody else noticed something similar?

2) Is there a safe procedure to temporary regress the firmware in order to confirm that this indeed was what caused the malfunction.
