Hash: ModemManager,modemmanager_t,kernel_t,system,module_request

Appears on first boot of a freshly installed Fedora 35 Workstation VM. Reporting manually as sealert/setroubleshoot seem to be broken and show no alerts. Booted with permissive to get system to boot and show all alerts (without permissive, it doesn't make it to gnome-initial-setup).
