Description

Originally reported at: https://bugs.freedesktop.org/show_bug.cgi?id=84994 Please refer to the original bug report if more details are needed.

This bug re-procedure at [Snappy] ModemManager 1.6.2-4. Snappy Ubuntu core 16

When hibernating, ModemManager keeps the state of the modem (MBIM open), but the modem itself gets fully reset and needs an explicit new MBIM open, or otherwise the MBIM port will keep on saying that it was not opened.

Version: 1.6
