[Bug 249932] graphics/drm-fbsd12.0-kmod: panic on certain graphics operations

--- Comment #7 from Martin Birgmeier <d8zNeCFG at aon.at> ---
I have recompiled head @ r366217 and then all (my usual) ports @ r550470. Then
cloned drm-kmod and set DRM_DEBUG_MM. uname -a shows, amongst others, "FreeBSD
13.0-CURRENT #0 r366217M".

Running make in drm-kmod yields the error below.

How can I proceed?
