Description Tristan Jones 2016-09-13 06:33:47 UTC

First off, I am fairly sure I am not filing this bug correctly, so I apologize in advance. 

The issue I have is that any time I try to boot using the 4.7 kernel, I completely loose all video output. 

Kernels 4.6, 4.5, and 4.4 all boot perfectly fine. But 4.7 just gives me a black screen. 

I have also tried several distros to include opensuse tumbleweed, fedora, and arch. All distros give me the exact same result. 

I can successfully boot kernel 4.7 if I use the nomodeset parameter. 

I personally do not own another video card to test if other video cards work, but I do have a friend who owns a GTX 760 that seems to work just fine. So I am thinking that this may be either a problem with the GTX 900 series cards or perhaps the 970 in particular. 

And in case it matters, I am using display port out to a 1440p screen.

Could you please provide the output of dmesg?
I would guess that you are experiencing the same issue as https://bugs.freedesktop.org/show_bug.cgi?id=94990 (even if 4.6 worked for you, which is interesting…).
