--- Comment #16 from Joel Sass sass.joel@gmail.com --- Created attachment 139134 --> https://bugs.freedesktop.org/attachment.cgi?id=139134&action=edit Here's the kernel .config I used for making the kernel
Key changes:
I added AMDGPU module, checked all 4 boxes. Looks like amdgpu.dc switch is gone, assuming that's intentional.
I also checked the optimization for Intel Core 2/Xeon processors kernel checkbox instead of generic x86
