Comment # 3 on bug 1130702 from Jonathan Rivrain

I had the same issue, while using btrfs.
And this happened again with todays's zypper dup

I hangs here:

The last time, I sorted it out by issuing the systemctl try-restart in another
terminal, but this time it does not work.
I have an un-ususal partition setup, my root being on two partitions.
