When I updated my stable/13 machine from source, from
March 16 to March 30, DRM was broken (did nothing).
Rebuilding graphics/drm-fbsd13-kmod fixed it.

So there was an ABI break in this time window.  This entry from
UPDATING implicates LinuxKPI changes as a likely candidate:

        Bump __FreeBSD_verion to 1301501 after merging LinuxKPI and
        net80211 changes in order to help out-of-tree consumers to deal
