Hardware: Lenovo Thinkpad Edge E145 00:00.0 Host bridge: Advanced Micro Devices, Inc. [AMD] Family 16h Processor Root Complex 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8240 / R3 Series]
This system works fine with the Radeon driver. With amdgpu and CONFIG_DRM_AMDGPU_CIK=y , it works until the next suspend-to-ram cycle. Then the system comes up but the screen remains dark.
See attachment for kernel logs. The same thing happened earlier when I tested AMDGPU with 4.8.x kernels.
