Hello: On a system now running: 14.0-CURRENT FreeBSD 14.0-CURRENT #0 main-d6327ae8c1: Sun Jan 24 14:16:54 EST 2021 amd64 (src+ports updated at midnight US EST) with PORTS_MODULES="drm-current-kmod gpu-firmware-kmod", starting the system _without_ loading drm results in a usable system. Loading drm - whether via kldlist in rc.conf or by kldload at the console immediately after start-up - instantly crashes the system; the screen goes blank and the lights on the monitor report no signal from the system. There is nothing in dmesg.boot. In messages I find (75 lines follow): Jan 24 17:35:22 jerusalem kernel: [drm:drm_core_init] Initialized Jan 24 17:35:22 jerusalem kernel: [drm] radeon kernel modesetting enabled.
