Hope the information is useful

I'm seeing the same *ERROR* lines on suspend/resume on one of my laptops, and the laptop panel stays black. Does that match your problem, or what did you mean by "broke the handling of power management"?

For the former, that matches the problem I encountered. 
About the line "broke the handling of power management", I noticed more fan noise than usual but it may be something else. It will be nice to optimize that power management if possible.

And you're saying suspend/resume broke around May 2nd for you? Do you happen to remember a commit before that where it worked for you?

Last commit that worked prior to the breakage was on 20170410. I just updated to the recent 20170511 which seems partially resolving the issue but the error message below still remains.

[22328.935171] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed
[22328.935217] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed

I'm still unclear as to the symptoms you're seeing. E.g., are the *ERROR* messages always accompanied by a black laptop panel? And does this only happen on suspend/resume, or also under other circumstances?

Yes, those *ERROR* message happened on suspend/resume followed by the black screen. Same errors also occurred when leaving the laptop in idle for a while as well.

Thanks for the clarification. Sounds like it's the same issue I'm seeing.

The XF86-video-ati driver is probably used. Kaveri does not work with this driver via DP. I have a black screen too.

I no longer own Asus X550Z which broke few months ago, replaced by HP Envy x360 Ryzen 2500U 15 inch. Feel free to continue or close this report.
