Comment # 2 on bug 901122 from Gerald Pfeifer

Sorry for the delay, this has proven hard to test.  Doing some
extensive testing over the last 24 hours I can confirm that with
a similar script:

case $1 in
    resume|thaw|post)
        sleep 10 ; /usr/bin/systemctl restart ModemManager.service > /dev/null
    ;;
esac

it mostly� works on Factory (kernel 3.17.4-1-default, ModemManager
1.4.0-1.1.x86_64).  

It does NOT WORK WITHOUT this script.


�Mostly since I did have one failure after a longer suspend-to-RAM, where
I had to restart ModemManager manually.  That was one out of twenty cases,
though, and other long suspensions did resume just fine.
