5 seconds on irc and I've found the splat ...
drm_properties need to be created at driver load time, upfront. You can attach them to hotpluggable drm_connector objects later on, but only before calling drm_connector_register().
The warning exists because i915 had the same bug :-) -Daniel

I'm getting the attached WARNING splats since amdgpu dropped its load callback. They're from
WARN_ON(!dev->driver->load && dev->registered && !obj_free_cb);in __drm_mode_object_add.
I'm not sure how to address this, since obj_free_cb is always NULL here, and I don't think MST connectors getting added after dev->registered is set can be avoided?
I need the full splat, otherwise can't tell you what's going wrong. There's 2 cases:
hotpluggable stuff, which has the obj_free_cb set. Essentially MST connectors.
not-hotpluggable stuff, which is everything else. They don't have
obj_free_cb set. It's a driver bug to register those after the overall drm_device has already been registered and published to userspace.
