Bug ID: 215223 Summary: AMDGPU Driver with Radeon RX 6700 sometimes can not find display Product: Drivers Version: 2.5 Kernel Version: 5.15.6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: reznov90210@gmail.com Regression: No

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.

Sorry for long delay. I have not got this problem for about 2 weeks (and can not get logs). But today, it was appeared again. Now I have attached logs. I have a problem with Displayport.
