Bug Description
When I boot a Dell Inspiron 7559 with an external monitor connected to the hdmi port, it usually shows only a blank screen after grub and I have to hard power off the laptop. The issue is present when the bios and grub are in mirror mode to both screens. I can see the following stack trace in journalctl:
syslog contains:
kernel: Missing switch case (6) in intel_prepare_
This occurs with both a Dell U2515H using an HDMI cord, and a HP Compaq LA2405wg connected via HDMI-to-DVI adapter.
WORKAROUND: Keep the monitor unplugged until the Ubuntu loading screen shows up.
WORKAROUND2: Remove "splash" from kernel command line parameters by editing /etc/default/grub file.

This is a fresh install. I have modified grub defaults to include "acpi_osi=!Windows 2015" But I tested without the acpi_osi parameter and see the same issue although the system now randomly crashes later on.
