I too get the Failed to start Load Kernel Modules error message during the boot process. The system seems to run fine though but I still want to fix this issue.
When I use journalctl I get this output:
systemd-modules-load[245]: Failed to find module 'vfs_monitor'
$ uname -r
5.10.49-1-MANJARO
$ modinfo vfs_monitor
modinfo: ERROR: Module vfs_monitor not found.
is part of the deepin-anything package, and the related module load configuration is located in /usr/lib/modules-load.d/anything.conf … Did you try reinstalling the package, is your system fully updated?
