Seems we have some reports in regard of networkmanager 1.4.0. Therefore I've downgraded now back to 1.2-series: https://lists.manjaro.org/pipermail/manjaro-packages/Week-of-Mon-20160829/008368.html This also means I've to rebuild all my custom-images of all six install medias I've created yesterday and reupload. Did I miss something else?
