Hm, that's pretty strange that you can't reproduce this any more. We check this has_edp stuff once at boot and then never touch it again.
Actually, I think I just figured out how to reproduce it: try to suspend with the micro-DP <-> VGA dongle, and attached to the screen. The suspend will fail, and the VGA screen does *not* come on again, and the messages happen.
But I didn't have drm.debug on this time - but I suspect that Chris will now be able to reproduce it easily with that information.
This time it also seems to be preceded by this message:
[drm:intel_cpt_verify_modeset] *ERROR* mode set failed: pipe 0 stuck
but that didn't happen last time so it may or may not be related.
