I have a problem with RX6700 connected to monitor using display port. It happens in 60% cases, while kernel booting i see some init messages and get black screen without signal, so i need to reset my system.
As i understand, this happens because AMDGPU can not find current display, connected to display port.
(WW) AMDGPU(0): No outputs definitely connected, trying again...
If system is booting, i haven't got any problems. I can watch videos (with HW acceleration) or playing games.
I have also tested on 5.13.x kernel with same result.
When i try to load Windows, i haven't got this problem.
What's more strange, that connecting to HDMI solves this problem and linux kernel proper initialize my display.
