I think I may be seeing this now - happens sometimes (but not reliably,
unfortunately) running compiz and exiting fullscreen games such as xmoto or
after running e.g. glxgears when invoking a compiz effect that involves full
buffer swaps, such as the alt-tab switcher.

I don't understand why DRM_WAIT_ON seems to constantly get interrupted by a
signal before it hits the three second timeout. Also, I can't seem to reproduce
this using the DRM from the 2.6.24 kernel, so it seems to be a DRM regression
that I'm trying to bisect, but it's slow progress.

Is this in line with your observations, and/or have you made any new ones?
