I replaced the new Radeon DRM driver from the Git kernel with the Radeon 
DRM driver from the kernel 6.11. (cp -R 
linux-6.11/drivers/gpu/drm/radeon a/drivers/gpu/drm/)

It compiles without any problems but unfortunately the kernel doesn't 
boot either.

Have you tested the new Radeon DRM driver with AMD Radeon graphics cards?
