Hi Ronald

I have a few things for you to test to me:

- can you check if your userspace is not trying to mirror or extend your
desktop to 2 monitors? if so disable one. By the logs I can see that both GPUs
have one CRTC and one plane enabled so maybe the mux is not working and both
GPUs are driving/trying to drive the same panel

- can you disable the AMD GPU in BIOS or blacklist the module and test it?

- can you apply this patch
https://bugs.freedesktop.org/attachment.cgi?id=142181 on top of drm-tip and
test it?(with AMD GPU still disabled)

- can you apply this patch
https://bugs.freedesktop.org/attachment.cgi?id=142181 on top of drm-tip +
https://patchwork.freedesktop.org/series/50843/ and test it?(with AMD GPU still
disabled)

Thanks
