Package: modemmanager Version: 1.22.0-3+b2 Severity: important (Important as this is problematic in locations where automatically enabling a GSM/LTE radio can cause security issues, like airplanes)
(not sure of network-manager, modemmanager or r gnome issue, please reassign if needed. Observation: On every suspend, ModemManager increments the number after "modem", e.g [modem3] -> [modem4] This might be a hint that this is a ModemManager issue redecting the same hardware as different modem on resume, though the device name (wwan0mbim0) stays the same. I'm using gnome-shell to deactivate the modem by clicking the icon for the mobil connection, and I see that the connection is disabled. syslog: If using the gnome-shell button to disable the complete mobile network stack, gnome will tell "no wwan adapter found" but in this case the disable state survives the suspend to ram. Observation2: When stopping ModemManager manually before systemctl suspend, the state is correctly retained, so I think this is a ModemManager thinking this is a new modem and enable it by default issue. When re-starting modemmanager manually, it will "reset" the number after modem to 0.
