the full dmesg

I have an AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx laptop.

After set and apply the orientation in display settings, the laptop's display rotates to the orientation and works.
However, I can see the amdgpu module hits the error in dmesg during the rotation: "[drm:generic_reg_wait [amdgpu]] ERROR REG_WAIT timeout 1us * 10 tries - optc1_lock line:553" and the warning message: "WARNING: CPU: 6 PID: 684 at drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c:195 generic_reg_wait+0xeb/0x160 [amdgpu]".
