Hm? For a test scenario I could force to get an error I got before, but the original script I'm using did it correctly, not the way I've done it for this test scenario. Before building the kernel and headers I rebooted and then I build the kernel with "No Forced Preemption (Server) (PREEMPT_NONE)" and got no error when installing the headers. Perhaps there was something very wrong with it and the reboot solved it. In the evening or tomorrow I try to build a "Fully Preemptible Kernel (RT) (PREEMPT_RT_FULL)" again.
