The video started lagging behind the audio as these crashes were popping up. ...later... Actually, assuming it is the same crash, I'm getting these pop-up without watching a DVD, so that seems to be unrelated.

If we disable the pipe, and then try to execute a WAIT_FOR_EVENT it will block indefinitely and cause a GPU hang. We attempted to fix this in commit 85345517fe6d4de27b0d6ca19fef9d28ac947c4a (drm/i915: Retire any pending operations on the old scanout when switching) for the case of mode switching, but this leaves the condition where we are switching off the pipe vulnerable. There still remains the race condition were a display may be unplugged, switched off by the core, a uevent sent to notify the DDX and the DDX may issue a WAIT_FOR_EVENT before it processes the uevent. This window does not exist if the pipe is only switched off in response to the uevent. Time to make sure that is so... Along with the additional patches hinted at for SNA.
