When plugging my laptop (Lenovo E14 Gen3, Ryzen 5500U) amdgpu spams the
journal, and I can no longer run two screens at 2560x1440. This started on
2/15/2022 after updating. I have been able to get both screens working now, but
I have to run one at 1080p and one at 1440p. It used to work great with both at
1440p.

In the one log file (it's rolled a few times) I got the following which seems
to show once per error.
grep -c drivers/gpu/drm/drm_dp_mst_topology.c messages
177772
