Doom (2016) GL hangs due to SDMA on GFX10

[  123.543583] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout, signaled seq=13738, emitted seq=13740
[  123.543657] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process DOOMx64.exe pid 2022 thread DOOMx64.ex:cs0 pid 2061

This kernel patch [1] doesn't fix the hang, but AMD_DEBUG=nodma fixes it!
