It fails differently with locally built drm-kmod. I wrote about that
in the bug report comment #8:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278930#c8

How I built drm-kmod:

1. download and extract src.txz and ports.txz from the 14.1-BETA2
amd64 folder at FreeBSD FTP server
2. cd /usr/ports/graphics/drm-kmod && make install
