Status in linux package in Ubuntu: Confirmed Bug description: 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.
