@sloeckle Just for clarity I was wrong in my post. If you are running FOG 1.2.0 the newest kernels you can run must be less than version 4.4. That means you will need 4.1.X and less than 4.4.0. The kernels 4.4 and newer requires code that only exists in FOG 1.3.0.
Your final answer may be to upgrade to the 1.3.0-rc7 (or what ever is the latest in the 1.3.0 series.
