[drm/amdgpu] Driver crashes on 5.13.9 kernel

[Skyler Mäntysaari]

I have tried kernel 5.13.13, without any difference and I haven't tried with an older kernel, as this hardware is that new that I have very little faith in less than 5.x kernel would even have support for the needed GPU.

What do you mean with git bisect? I have checked that the crash happens somewhere in the monitor connection code:
