I tried kernel 4.3.rc4-2.1.gefc53bd-default, but boot stopped again. In journalctl I found: "could not load Kernel modules". In /user/lib/modules-load.d I found: sg.conf (# load sg module at boot time sg) All other "modules-load.d"-files, mentioned in "systemd-modules-load.service", are empty or can not to be found on my computer. Can this cause my problems? Can I try to comment it out or delete it? This is my last attempt and I do not want to waste Your time with such archeological problems. Far earlier kernels skipped starting services, if there were dependencies, and started them later with success. Now systemd deletes them and they must be started by hand (YAST). Is this true? I can see his timing-problems for a long time and I don't have the idea, that this is related to localmodconfig or localyesconfig, but I will try it with my next kernel. Thanks to Takashi Iwai for his always quick and involved replies.
