kernel boottime dmesg output with error

With kernel 5.10.4, 5.10.5 there is regression with amdgpu driver and 2 monitors.
Only first monitor shows anything under kde plasma and sddm, and console terminal, the second one doesn't display anything after boot.
Up to 5.10.3 everything was fine and 2 monitors.

CPU: AMD Ryzen 9 3900X 12-Core @ 24x 3.8GHz
GPU: AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.10.3, LLVM 11.0.0)

In dmesg I see and error 
drm:dm_restore_drm_connector_state [amdgpu]] *ERROR* Restoring old state failed with -12
