After booting into runlevel 5 the keyboard is not functioning.
CTRL-ALT-BACKSP does not work to restart the X-server. CTRL-ALT-F[1-6] does work. In these consoles the keyboard is funtioning so I'm able to log in as root. After 'init 3' followed by 'init 5' I'm able to log in in X.
Here are some additional informations:
