Modem stuck in unknown state

[Aleksander Morgado]

Hey Brian,

> I am using Sierra Wireless MC7455 modems and randomly when I try to create a bearer I get the error GDBus.Error:org.freedesktop.ModemManager1.Error.Core.WrongState: modem in unknown state.  Once I get this error all commands besides getting information give either this error or time out.  If I do a mmcli –m 0 I can see a bearer but if I try something like mmcli –b 0, I get “couldn’t find bearer”.  No logs seem to be generated even in debug mode.

ModemManager 1.10.0 is a very old version, and it isn't even the last
release in the 1.10.x series. Please retry with ModemManager 1.12.10
and send us ModemManager debug logs (see
https://www.freedesktop.org/wiki/Software/ModemManager/Debugging/) if
you can still reproduce the issue.
