CID: 201706-25581 Dell Inspiron 7577

Steps:
  1. Install Bionic + update with LiveUSB
  2. Boot to the desktop
  3. Poweroff / restart the system from the menu in the upper right corner

Result:
  The system will hang before reaching the splash screen. The ctrl + alt + prtscr + b magic key combination is still alive. This is the last thing that could be seen from syslog:
