Xorg log

Description of problem:

After updating to latest kernel, I'm unable to log in using the the Gnome default session (using Xorg). Wayland work fine. 

When using "startx", system seem to go into a kernel panic, seemly caused by Nouveau.

Version-Release number of selected component (if applicable):

4.3.3-300.fc23

How reproducible:

100%


Steps to Reproduce:

1. Boot with said kernel
2. Log using any Xorg based session

Actual results:

System will hang (with something looking like a kernel panic when using command-line).

Expected results:

Gnome desktop show.

Additional info:

I'm on an Optimus enabled laptop (Core i7-4500U + nVidia GTX 820M)
