the dmesg
I have an AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx laptop.
After system is booted and plugged the HDMI cable, the laptop's display had
been blurred a while than came back again, and the extended display also
worked.
However, I can see the amdgpu module hits the error in dmesg:
"[drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 1us * 10 tries -
optc1_lock line:553" and the warning message.
