https://bugs.freedesktop.org/show_bug.cgi?id=103102 --- Comment #6 from Hadrien --- I tried Phoronix kernel image from Alex Deucher's drm-next-4.15-dc Git branch. I still get the same problem with and without amdgpu.dc=1. Oct 9 21:29:12 c18 kernel: [ 32.199451] [drm:amdgpu_vce_ring_test_ring [amdgpu]] *ERROR* amdgpu: ring 14 test failed Oct 9 21:29:12 c18 kernel: [ 32.199461] [drm:amdgpu_resume_phase2 [amdgpu]] *ERROR* resume of IP block failed -110 Oct 9 21:29:12 c18 kernel: [ 32.199471] [drm:amdgpu_device_resume [amdgpu]] *ERROR* amdgpu_resume failed (-110).

Maybe there are changes in another impacting amdgpu?
