CPU: Intel i7-6700
GPU: XFX Radeon RX 570 connected to monitor via DisplayPort using amdgpu
Steps to reproduce: If running linux-current 5.10.4-165, turning off my monitor or disconnecting the DisplayPort cable I use results in me being unable to get anything to show up. My monitor does not even detect any video coming to it. Switching to a virtual terminal does not help and a full reboot appears to be required.
The issue does not occur after having downgraded to 5.10.2-164.
