I may have spoken too soon. I'm non-deterministically experiencing the basic
symptom of hang on resume with a blank screen, sometimes with the backlight on
and sometimes without, but I no longer get the traceback in logs, so I can't
tell if it's mostly the same bug but without tripping the failure mode that
causes it to log, or if there's an unrelated suspend/resume bug. Switching to
the OpenGL 3.1 compositor has definitely made that error message stop appearing
in my logs though.
