Kernel messages

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.
