Thanks for your answer! 1. There are no "desktop"-kernels in repsitory/Kernel/Head or /Kernel/standard anymore. So I will wait or try a default-kernel later on. 2. Now I am used to built my own kernel (act. version 4.1.10, localyesconfig, size 20,7 MB, built-time 27 min) and this kernel is always working fine (with some timing-problems caused by systemd). So it must be a SUSE-specific problem and not a raid0.ko one. But, as I seem to be the only one with it, it should be dropped or closed. 3. Bug 938048 showed that my partition-table is "semi"-corrupt or with some faults, so that parted can not deal with it. Luckily I could reach some changes in YAST-storage, so that I could use it again. The booting-problem occurred at the same time, so I guessed, there could have been a policy-change in SUSE-tumbleweed. I'm not so familiar with changings in a working raid-system, but sooner or later I will have to change it into raid1 or drop raid completely. I have no idea how to do it yet, so I prefer, to do nothing.
