Not sure why this shows as a fatal error, because it isn’t; a warning, at best. I ran into the same issue when the 6.2.x kernel series was released. Since I’m also using the LTS and 5.15.x series kernels, I left my dracut config files alone. My GPU pass-through works just fine on all (3) kernels.
I have a thread open on this - Conditional module loading with dracut - but haven’t gotten anywhere.
