You are getting a GPU lockup.  Is there any particular trigger?  A specific app that tends to trigger it?  Updating mesa may help if you are running an older version.
Comment 3 Andre 2016-08-09 22:00:14 UTC
I'm using mesa 12.0.1
The only thing that works is downgrading kernel to 4.5

had the Problem with kernel 4.6.2 too

I'm on Sabayon

Can you bisect?
Comment 5 Andre 2016-08-09 22:21:39 UTC
eh, do what? ..may if you give complete howto for my sabayon/gentoo system?

Bisecting is a process for determining which specific commit in a project caused a regression.  Google for "linux kernel git bisect howto".
