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.

[   19.998488] [drm:amdgpu_device_init.cold [amdgpu]] *ERROR* sw_init of IP block <vega10_ih> failed -12
[   19.998490] amdgpu 0000:0c:00.0: amdgpu_device_ip_init failed

[   19.998493] [drm] amdgpu: finishing device.
[   19.998601] [drm] amdgpu: ttm finalized


I've attached my dmesg as well.

Thanks,
