The problems remains with Linux 4.18 and Linux 4.19 kernels. I am unable to use AMD RX 460 and AMD RX 550 on my x64 Linux platforms.
I've installed Windows 10 in the same machine along with win10-64bit-radeon-software-adrenalin-edition-18.10.1-oct18.exe and under Windows the same RX 460 card *works fine* and I am able to run OpenCL applications. The driver is hanging since kernel 4.15, I am getting: [ 33.504100] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR* [CRTC:42:crtc-0] flip_done timed out [ 43.744094] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:42:crtc-0] flip_done timed out [ 53.984089] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CONNECTOR:54:HDMI-A-1] flip_done timed out [ 64.224036] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [PLANE:40:plane-4] flip_done timed out [ 64.224141] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* amdgpu_dm_commit_planes: acrtc 0, already busy And after commit: drm/amdgpu: defer test IBs on the rings at boot (V3) 2c773de2ecb8c327f2448bd1eecad224e9227087 <https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v4.18-rc4&id=2c773de2ecb8c327f2448bd1eecad224e9227087> I get with kernels 4.18 and 4.19 as well as Ubuntu 18.10 stock kernel (can't even install Ubuntu 18.10 because it hangs with amdgpu): [drm:gfx_v8_0_ring_test_ib [amdgpu]] *ERROR* amdgpu: IB test timed out.

Is there any hope on getting this fixed?
