Suspend fails on Ubuntu 18.04 when mobile network connected and no WiFi
connection.
Ubuntu 18.04, Thinkpad X240, Sierra modem
Reproduced on 4.15 and 4.18 kernel.
The bug is triggered only when there is no WiFi connection. After waking
laptop from suspend ModemManager stops working and after that I cannot suspend
anymore. When it happens mmcli -L gives:
Found 1 modems:
/org/freedesktop/ModemManager1/Modem/9 [Sierra] MBIM [1199:A001]
And mmcli -m 9:
Status | lock: 'none'
| unlock retries: 'sim-pin (3)'
| state: 'registered'
| power state: 'on'
| access tech: 'gprs, lte'
| signal quality: '0' (cached)
After a few attempts to restart ModemManager and suspend it starts
working. But only for one suspend. After one suspend I need to do the
whole procedure again.

On Ubuntu 16.04 suspend and ModemManager used to work flawlessly.
