--- Comment #59 from Spencer (smp@nandre.com) ---
Is this a custom built kernel? Is amdgpu built into the kernel or enabled as a module? In the former case, is all required firmware also built into the kernel? In the later case, is all required firmware available on the initramfs (if amdgpu is incorporated in the initramfs)? The required firmware files are listed here:
It's a custom, but I have them all builtin.
grep navi10 .config && echo amdgpu/navi10_{asd,ce,gpu_info,me,mec2,mec,pfp,rlc,sdma1,sdma,smc,sos,ta,vcn}.bin
