Slowroll last 2 dup's changed kernel from longterm to default - check if you use longterm

English Install/Boot/Login

The last 2 slowroll releases installed both longterm and default kernels on my slowroll machines.

If you list /boot and see default - you do not have longterm kernel

the cure is

zypper rm kernel-default
zypper in -f kernel-longterm
reboot
