System Information
Intel Core i5 3450 / Radeon RX480 8 GB / 8GB RAM 1600 MZ

Blender Version
Broken: 2.79 5bd8ac9
Worked: 2.78 / 2.79

Short description of error

New installation of Win 10 64 Bit + new Blender Version 2.79 via Steam.
First it worked. I tried to render a high poly object with high resolution textures and I got "Loading Render Kernels: This can take a few minutes the first time". After a few seconds Blender closed. Then I tried to render an older file from experimental 2.79 and it also doesnt work. I could only render objects in the new Blender Version 2.79 (but the first Obejct I called was created in 2.79 too ? anyways..). And now I can't render anything. But only with GPU, I still can render with CPU.

I deleted and Installed Blender again (x 2)
I deleted my AMD RX400 Series driver and installed it again after it still doesnt work
I deleted the Steam Version of Blender and downloaded it from the Website and installed it

I still can render with 2.78

Tomorrow I try to install Win 10 again. If it works I will do some tests otherwise I try to install Win 7 again and test it again.

Maybe you have some tips for me?

It is hard to tell what's going on with only such knowledge. Some random ideas:

All our benchmark machines have 12Gb RAM, never tried on lower memory machines. So try watching memory usage in system monitor when you start rendering.
Try rendering from the console: path\to\blender.exe -b path\to\scene.blend -f 1 and see if that works.
Try installing latest drivers from amd.com site (if you did that, try re-installing them)
Last but not least, do the following from command line: path\to\blender.exe -b --debug-cycles path\to\scene.blend -f 1, copy-paste log to notepad, save as file and attach it here.

One thing i didn't understand, you mention 2.79 as broken and as working, can you elaborate on that?

Could be a duplicate of #52645, which was closed for some reason...

"One thing i didn't understand, you mention 2.79 as broken and as working,"

"First it worked"

I don't know, I described the problem in the first post. Which infos do you guys need so that I can help you.

Well, we need all information we need to reproduce the issue from our side :) That ensures we can fix the issue efficiently.

Ok, so if same Blender worked and then it stopped working, odds are that it's not really a Blender fault.

Did you try non-steam builds from https://www.blender.org/download/ ? If not, please do so.

I'll see if I can shed a little light on what he's trying to say. I'm having the same issue.
AMD RX480
16GB RAM
Blender 2.79 Official and Daily builds.

It seems my crash occurs when there is a normal map node attached to my shader tree. SSS works fine as soon as I hook up my normal map node, it compiles render kernels for a few and then closes. I'll run the cycles debug and see if i can get you a report in a few minutes here.

Here is the cycles debug log. I'm going to try rolling back to the driver listed in the bug report Mai Lavelle posted and will be back with results.

Just incase either sergey or mai want to look at this in further detail, can you post a minimal .blend that'll trigger the issue for you? (if you used textures be sure to pack them)

I just open Blender and I try to render.

Ok some more info. Amd 17.7.2 and 17.9.1 crash. Amd 17.7.1 is good to go and renders perfectly. Just like the post Mai mentioned.

Where can i download it? Here I can see 17.7.2 and 17.9.1 http://support.amd.com/de-de/download/desktop?os=Windows%2010%20-%2064

I have this problem but rendered view in the viewport works just fine. This happens with every scene, even blank scenes. I upgraded to 1.7.7.2 AMD drivers a while ago and it started happening out of nowhere. I am installing the absolute latest available to see it will help the problem. I have an AMD RX480 4gb on Blender 2.79

Updated to 17.9.3 and it works but it is incredibly slow to the point where i might as well just render with cpu

Braden commented

nevermind that, just tried rendering a simple scene with 2 objects and a lamp failed.

17.1.1 seems to work for a lot of people, give that one a whirl
