Tried just now with 12-STABLE installed using FreeBSD-base and all kmod
packages recompiled in a jail that was created from the same obj/usr as
the 12-STABLE base packages. In other words:
The build host is running 12.1-RELEASE-p3. On it I fetched 12-STABLE and
compiled world and kernel. Then packaged both into FreeBSD-base packages
to install on the destination desktop. Then I created a new poudriere
jail using the same 12-STABLE usr/obj. Then I used that jail to build
drm-kmod, drm-fbsd12.0-kmod and gpu-firmware-kmod. Then I reinstalled
the base (world/kernel) on the destination desktop using FreeBSD-base
packages and reinstalled on it the three kmod packages recompiled with
poudriere.
The result is (almost) exactly the same as with 12.1-RELEASE-p3. The
screen goes blank and to sleep after a few seconds. The ssh session
survived:
