ModemManager waits to get all modems properly disabled and all modem objects removed; so it is likely that a bug in that code prevents a proper shutdown of ModemManager. The fix would be to find that bug and fix it; but a preventive measure with a max time to wait to within ModemManager for the properly shutdown could be implemented.
If it is easily reproducible, can the reporter launch MM in debug mode and try to reproduce it?
