Thanks a lot to forums.opensuse.org
As we now found out the boot/shutdown problems where just caused by systemd so, while booting (on the grub menu) you can switch to systemV via F5 and that just worked.
So now we must talk about making systemV default again, so just look what SUSEhelp post us via IRC
<SUSEhelp> By default, openSUSE now boots using systemd. In case of trouble, you can switch back to the old way using sysvinit by pressing the F5 key on the boot. If you want to switch to sysvinit permanently, install the sysvinit-init package. To switch back to systemd, reinstall the systemd-sysvinit package.
So as easy as it is told:
zypper in sysvinit-init Problem: sysvinit-init-2.88+-66.58.2.x86_64 conflicts with namespace:otherproviders(sbin_init) provided by systemd-sysvinit-37-3.4.1.x86_64 Solution 1: deinstallation of systemd-sysvinit-37-3.4.1.x86_64 Solution 2: do not install sysvinit-init-2.88+-66.58.2.x86_64 Choose from above solutions by number or cancel [1/2/c] (c):
Now take solution 1, it will replace systemd
