I've made changes to the udl unload path: drm: Fix drm_release() and device unplug https://cgit.freedesktop.org/drm/drm-misc/commit/?id=1ee57d4d75fbc74bb2ae601c8f334219165ef276 drm/drv: drm_dev_unplug(): Move out drm_dev_put() call https://cgit.freedesktop.org/drm/drm-misc/commit/?id=ba3bf37e150a99b51b13f5cebf89715685d21212 I don't know if these could be the cause of your problem.
