I have a Dell Inspiron 5548 and I made a clean install of Ubuntu 16.04 64-bits on it these past days, with subsequent updates, obtaining the following error on Xorg:
[ 21.492120] [drm:gfx_v8_0_ring_test_ring [amdgpu]] *ERROR* amdgpu: cp failed to lock ring 0 (-2).
[ 21.492154] [drm:amdgpu_resume [amdgpu]] *ERROR* resume 4 failed -2
[ 21.492178] [drm:amdgpu_resume_kms [amdgpu]] *ERROR* amdgpu_resume failed (-2).

Guilherme Versiani, thank you for reporting this and helping make Ubuntu better.
1) Do you have an actual usability issue or you just notice these errors in the logs?
2) To clarify, which updates were applied specifically when this issue started to happen?
