Thank you for performing such extensive testing. Glad to learn there was no big surprise. The "missing modules.softdep and modules.devname" warnings happen with the distro kernel as well. I tried to find out where this comes from but have not been successful. Could you check to see if there are any "residuals" in /lib/modules after the plus kernel has been uninstalled? Also in /boot ?
