While investigating the runpm issues on my GP107 I noticed that something inside devinit makes runpm break. If Nouveau loads up to the point right before doing devinit, runpm works without any issues, if devinit is ran, not anymore. Out of curiousity I even tried to "bisect" devinit by not running it on vbios provided signed PMU image, but on the devinit parser we have inside Nouveau.
