After installing the update, I still have to restart ModemManager to get my Huawei ME906s-158 to work.

Sorry it's not working yet, to help narrow this down further could you:

mmcli --set-logging=DEBUG

then reproduce the problem (without restarting ModemManager!) and when the modem is no longer working:

journalctl -b -u ModemManager > /tmp/modem.log

and then please attach /tmp/modem.log so we can investigate.  Thanks!

Hello,

I Have a HP hs2350. It is using CentOS 7.2... I Know it is not the same setup. Nevertheless, I have the same issue from a long time with Suspend/Resume and modem.
Initially, I needed a complete poweroff of the laptop to reinitialize the modem.

I recompiled and applied patches from here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-494a721a73

I see improvement: 
* First tests I did Friday last week, everything was OK even after suspend resume....
* Now, after the WE, Monday, After suspend/resume, I get no connection. But effectivelly If I restart ModemManager, it works again! No shutdown required anymore.

I do not know what changed....

I attache the log (modem_after_restart_CentOS.log)
at 13h49 --> suspend+resume
No Connection anymore
at 13:56 --> restart Modem Manager; it redetect Modem.
at 14:00 --> reconnected

Regards, Marc

HP hs2350 on CentOS 7.2 with ModemManager/libqmi/libmbim patches from here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-494a721a73

ModemManager-glib-1.6.0-1.el7.centos.x86_64

After suspend/resume, no connection. Restart ModemManager --> it works again

at 13h49 --> suspend+resume
No Connection anymore
at 13:56 --> restart Modem Manager; it redetect Modem.
at 14:00 --> reconnected

My modem doesn't even connect anymore now, even after restarting NetworkManager. Will try a cold boot or maybe boot windows in between to reset it to a workable state, then fetching some debug logs.

nope, still not working after cold boot/windows in between (which connected fine).

I tested both with the packages in fedora 24 and in updates-testing, same result.
So could be a kernel bug.
