            Bug ID: 104437
           Summary: RX480 + SME  = amdgpu init failed + null dereference
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

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.

Same issue using 5.1.9, RX Vega 64 and Ryzen 2700x.

I've attached my dmesg as well.
