The error doesn't affect me but annoyingly force me to change the boot
option at grub menu failing which ends up in loopin boot process.

Title:
  After upgrade to Ubuntu 15.10, Systemd fail to boot

Status in systemd package in Ubuntu:
  New

Bug description:
  After successful upgrading to Ubuntu 15.10 from 15.04, restart system option couldn't boot, seemed in a loop, showing mouse pointer in the center of the screen for few seconds and then a blinking cursor at the upper left corner, instead. Used Ctrl+Alt+Del to reboot and selected Upstart option which successfully booted the system but showing a message like "Upstart; Error while reading from descriptor, broken pipe."
  On my next attempt to boot using default systemd option I observed a message like "Systemd(1) Failed to setup API Bus. Connection timed out." , and then saw a window saying like "running low graphic" and then went into the same loop.
  Now, I can boot using Upstart option only not the systemd option.

  I'm using Dell Optiplex 755 with NVIDIA 8400GS Graphic card,
  Ubuntu 15.10 is installed on a external HD connected with one of external usb port.
