Comment 24 for bug 2007633

I see that the error "amdgpu: Move buffer fallback to memcpy unavailable" comes from drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c. I downloaded the Ubuntu source code for 5.19.0-35 and compiled with the amdgpu_ttm.c from the Linux 5.19 snapshot on github. This eliminated the error and my Kaveri machine boots successfully with amdgpu. If that helps at all.

Though my Cezanne 5600G works fine with 5.19.0-35.
