<pre>I tried several kernels:
4.12.4: OK
4.12.5: OK
4.12.6: FAIL, but after 20 seconds the monitor displays something: pure garbage
4.12.7: FAIL, the monitor stays OFF
I'll attach the kernel logs.
Interesting part in 4.12.6:
Oct 5 20:56:21 c18 kernel: [ 37.277968] [drm:amdgpu_vce_ring_test_ring
[amdgpu]] *ERROR* amdgpu: ring 13 test failed
Oct 5 20:56:21 c18 kernel: [ 37.277976] [drm:amdgpu_resume [amdgpu]] *ERROR*
resume of IP block <vce_v3_0> failed -110
Oct 5 20:56:21 c18 kernel: [ 37.277983] [drm:amdgpu_device_resume [amdgpu]]
*ERROR* amdgpu_resume failed (-110).
Oct 5 20:56:21 c18 kernel: [ 37.277985] dpm_run_callback():
pci_pm_resume+0x0/0xa0 returns -110
Oct 5 20:56:21 c18 kernel: [ 37.277986] PM: Device 0000:01:00.0 failed to
resume async: error -110
There is a slight difference with more recent kernels, where the message
mentions ring 14 instead of ring 13 and some other functions too.</pre>
