This seems to be an issue in systemd udev 258.1. If the recent update is reverted to systemd udev version 257.8 then boot and tests work on Renesas SMARC EVK based on r9a07g044l2 apart from missing HDMI adapter and thus X11 fails to start. For some reason this is the only board with such issues. I will try to debug this further. Cheers, -Mikko
