Suspicious section from kernel 4.18.16 dmesg output:

Comment 3 Michel Dänzer 2018-10-01 09:33:00 UTC
Error -2 is -ENOENT, "No such file or directory", so the amdgpu/polaris11_mc.bin file is missing where the amdgpu module is loaded from (could be the initrd).

This is a configuration error, not a bug.

Thanks for your feedback! I'll communicate this back to Red Hat.
