Some more information: * if I start a debug-shell on a serial port, at some point the shell seems to freeze as well. * if I boot with sysvinit instead of systemd things work fine: - The system reboots even if an X11 console is active - During the shutdown, I can switch between text consoles and see log messages Any ideas?
