Title:
  DPLL2 override remains enabled after warm boot of Linux

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu Version Target: 18.04.1 LTS (bootable Ubuntu USB stick)

  Package Version Target: Unknown

  Expected: Windows S3 Sleep actions with two DisplayPort monitors using
  Intel integrated graphics should be able to work without issue after
  entering a Windows OS from a previously loaded Ubuntu session

  Actual: Windows S3 Sleep actions with two DisplayPort monitors using
  Intel integrated graphics will result in a BSOD event if a Windows OS
  is loaded after an Ubuntu OS session that was ended by a warm reboot
  action

  Description:
  Using a dual-boot Ubuntu/Windows 10 desktop computer environment with two 
native DisplayPort MB connections to the Intel integrated graphics solution and 
two DisplayPort monitors it was observed that performing a Windows S3 Sleep 
action will cause a "WHEA uncorrectable error" BSOD event if the first OS 
loaded is Linux and the second OS Windows is loaded using a warm boot action.

  Investigating this BSOD event further it was determined that this issue is 
specific to the "Linux->warm boot->Windows->S3 Sleep" sequence as long as two 
DisplayPort monitors are connected to the desktop computer's DisplayPort MB 
connections. 
   
  A deeper investigation of the cause of the BSOD identified that upon 
unloading Linux the DPLL2 override bit remains enabled and will cause a 
subsequent Windows desktop environment to be vulnerable to failure if it makes 
use of two DisplayPort-connected monitors.

  This issue can be reproduced using OEM hardware from either of Lenovo, HP, or 
Dell.
  This issue was first observed on the Q270/Q370 Intel chipset and the Intel 
530/630 Graphics hardware.
  Calvin Hartwell of Canonical has been made aware of this issue and been 
provided issue details and video evidence.
