3. Looking through the crash in sehellion's comment 45:

gfx_v9_0_ring_test_ring+0x19e/0x230 [amdgpu]
amdgpu_ring_test_helper+0x1e/0x90 [amdgpu]
gfx_v9_0_hw_fini+0x299/0x690 [amdgpu]
amdgpu_device_ip_suspend_phase2+0x6c/0xa0 [amdgpu]
amdgpu_device_ip_suspend+0x44/0x80 [amdgpu]

amdgpu_device_gpu_recover+0x7b/0x7a3 [amdgpu]
amdgpu_job_timedout+0xfc/0x120 [amdgpu]

We see gfx_v9_0_ring_test and gfx_v9_0_hw_fini which both come from:

There's a 5.1-rc1 commit in this file pertaining to a "wave ID mismatch" that
could cause deadlocks.
