Of note, I just compared to a DIFFERENT system I own, also running amdgpu ...
the spam is there too but dumping real information (still, spam is undesired)

These particular messages are fixed in current kernels.

"current kernels", more specifically?
(Fedora runs pretty bleeding edge kernel-wise)

If we have a "fix in kernel version X", and a different bug report to duplicate
against, we can close then then?

4.16 or newer.

I was only referring to the

  [drm] {1920x1080, 2200x1125@148500Khz}

messages. The "SADs count" messages are still there.

(understood) - so the SADs count is a bug to be fixed
(the comparison I provided against legit data is N/A here and anyway is fixed
in newer kernel versions)
