It's me, again.

With the branching for freebsd-12, the top-of-tree 
(aka freebsd13) has introduced knobs that prevent
the building and installation of drm and drm2.  These
knobs have been set to 't'.  Thus, my last world
update did not install the in-tree drm and drm2.
So, it seemed like a good time to switch to one of
the drm ports (as suggested by src/UPDATING).

graphics/drm-legacy-kmod is simply broken, which has
been previously reported.

graphics/drm-stable-kmod fills /var/log/messages with

Oct 30 14:50:35 troutmask kernel: fence_wait returned with error -512
Oct 30 14:50:35 troutmask syslogd: last message repeated 10 times
Oct 30 16:30:16 troutmask kernel: fence_wait returned with error -512
Oct 30 16:30:16 troutmask syslogd: last message repeated 4 times

It seems that setting WITHOUT_DRM_MODULE=t and
WITHOUT_DRM2_MODULE=t is premature.

Yes, I am aware that I can set WITH_MODULE_DRM and
WITH_MODULE_DRM2 in /usr/src.conf, and recover the
missing in-tree modules.  

PS: /usr/src/UPDATING spells the WITHOUT_* knobs as for
example WITHOUT_DRM2_MODULE while src.conf(8) documents
a WITH_MODULE_DRM2 knob.  I suspect UPDATING is wrong.

% find /usr/src -name \*.mk | xargs grep _DRM
/usr/src/sys/conf/kern.opts.mk:    MODULE_DRM \
/usr/src/sys/conf/kern.opts.mk:    MODULE_DRM2 \
% find /usr/src -name Make\* | xargs grep _DRM
/usr/src/sys/modules/Makefile:.if ${MK_MODULE_DRM} != "no"
/usr/src/sys/modules/Makefile:.if ${MK_MODULE_DRM2} != "no"
/usr/src/sys/modules/Makefile:.if ${MK_MODULE_DRM} != "no"
/usr/src/sys/modules/Makefile:.if ${MK_MODULE_DRM2} != "no"
