[drm/amdgpu] Driver crashes on 5.13.9 kernel

Hello everyone on the list,

I thought that this should probably be discussed here, so I came across weird issue to me which is driver crashing while trying to get one of my monitors working on Gentoo. I would like to ask here how that would happen that the Display appears to jump from DisplayPort-6 (physical port) to DisplayPort-7 (which doesn't exist physically)? Has anyone else experienced this?

It seems that the driver sees a rather large amount of inputs for the GPU, even though I only have 4, 3 of which are DisplayPort, and the issue monitor is also on DisplayPort.

Hardware:
CPU: AMD Ryzen 5800X
GPU: AMD Radeon RX 6800
System Memory: 32GB of DDR4 3200Mhz
Display(s): BenQ Zowie XL2430 (1080p), DELL U2414H (1080p), DELL U2415 (1920x1200)
Type of Diplay Connection: All are connected via Display-Port
