Description elegant.engelbart 2023-07-09 11:08:45 UTC 
Since updating to kernel 6.3.11, I don't get display output on my AMD iGPU (on Ryzen 7950X). Kernel 6.3.12 from testing shows the same issue. 6.3.8 and below work fine.

Jul 09 11:57:52 annie kernel: Console: switching to colour frame buffer device 480x135
Jul 09 11:57:52 annie kernel: amdgpu 0000:6d:00.0: [drm] fb0: amdgpudrmfb frame buffer device

More details:

Using the HDMI output on a ASUS proart x670e motherboard, ryzen 7950x. IGPU is set as primary video device in BIOS. An Nvidia GPU is present too but bound to vfio-pci on boot (kernel parameter)

Reproducible: Always

Steps to Reproduce:
1. Boot on the system
Actual Results:  
No video output, intermittent green flashing

Expected Results:  
Normal video output
