Research direction

No source file, test, or entry point is named. Start by reviewing the attached nvidia-bug-report.log.gz and reproducing the external-display connect/disconnect sequence on Arch Linux with the listed kernel and GPU. Done means the GPU shuts off after disconnecting the display without the reported vblank watchdog message.
