dmesg output after starting X session

While
- starting or running an X session
- using DirectFB to e.g. play movies in vlc or mplayer from a console login
circular locking dependency warnings appear in dmesg.

Afterwards, X can hang or crash outright but at other times does not appear affected.  Video output in framebuffer is always highly corrupted (not sure if this is a separate bug).

Problem gone with latest DRM and kernel RC.
