Hi Paul,
well that is rather odd, cause the patch you pointed out is just a code
cleanup without functional change.
Can you double check your bisect result again?
Thanks,
Christian.

I didn’t see the v2 message in my INBOX, but this commit 7c4e581a
(drm/amdgpu: simplify the bo reference on amdgpu_bo_update) should be applied
to current Linux 4.18-rc7 series, best before the Linux 4.18 release next
Sunday. Otherwise the screen is not updated when switching from EFI frame
buffer to amdgpufb, and GDM doesn’t start on the MSI B350M MORTAR (MS-7A37).
The problem is present in 4.18-rc1, and I bisected the branch
*amd-staging-drm-next* (with the meaning of good and bad reversed).
