This means that offb no longer finds the expected device, which prevents the Debian Installer from setting up its interface, at least on ppc64el. It might be better to iterate on all possible nodes, but updating the hardcoded device from "of-display" to "of-display.0" is confirmed to fix the Debian Installer at the very least.
