This time hibernation image is created, and laptop turns off after that. But - during the hibernation process screen goes totally white, process take approximately 15-20 seconds on ssd drive before netbook gets power-off. During resume hibernation image is read (it is possible to see percentage) and then screen goes white, and machine is in a locked-up state. I can do nothing but press power button to hard-reset the netbook. Moreover I foud only once an error message in kernel log: "Mar 28 01:36:54 eclipse kernel: [ 86.665473] [drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:39:crtc-0] flip_done timed out Mar 28 01:36:54 eclipse kernel: [ 86.828685] [drm:gfx_v7_0_ring_test_ring] *ERROR* amdgpu: ring 0 test failed (scratch(0xC040)=0xCAFEDEAD) Mar 28 01:36:54 eclipse kernel: [ 86.828698] [drm:amdgpu_device_ip_resume_phase2] *ERROR* resume of IP block <gfx_v7_0> failed -22 Mar 28 01:36:54 eclipse kernel: [ 86.828703] [drm:amdgpu_device_resume] *ERROR* amdgpu_device_ip_resume failed (-22).

I am not sure how much it is related but this could be usefull, tough. Kernel was booted up with amdgpu.dc=1. Any help is appreciated.
