Using drm-next in 11.2

[CL Moonriver]

I agree it sounds like a clash with older modules. Did you have
drm-stable-kmod installed or drm-legacy-kmod installed? If so, make
sure you remove them before. Sounds to me like what is probably
happening is you have modules from two different drm ports installed.
So I'd try a make deinstall inside drm-stable-kmod and drm-legacy-kmod
directories and see if that fixes anything.
