--- Comment #2 from Hadrien <freedesktop@psydk.org> ---
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.
