So what happens is that a mode is attempted to be set with no connectors.

That case is the other nonsense use of ->set_config I've curbed with all the fb helper fixes.

BUG_ON(set->fb && set->num_connectors == 0);

in drm_crtc_helper_set_config should catch this abuse of trying to set a mode with no connectors. So I'm still confused what exactly is going on in your box. -Daniel
