Description Asbjørn Sannes 2018-01-01 16:20:53 UTC
Created attachment 136470 [details] dmesg when not working When upgrading from linux 4.13.x -> 4.14.x the amdgpu failed to come up, often hanging my desktop computer. Ending the amdgpg bring up with: [drm:gfx_v8_0_ring_test_ring [amdgpu]] *ERROR* amdgpu: ring 0 test failed (scratch(0xC040)=0xCAFEDEAD) [drm:amdgpu_device_init [amdgpu]] *ERROR* hw_init of IP block <gfx_v8_0> failed -22 amdgpu 0000:0a:00.0: amdgpu_init failed After getting some help in #radeon we figured out that the culprit was that I had enabled SME (which the CPU Ryzen X1800 support). Got the same error on 4.15-rc6, but with additional null dereference in DC code.
