No, booting into an older Kernel (3.5.0-16-generic) didn't solve the problem. Worth noting is that it seems if I disable the following line in /etc/defaults/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" the system has also no boot problems. But the shutdown process doesn't look as pretty as before.
