Title:
  "unexpectedly disconnected from host boot status daemon" under high
  memory load

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The hardware is Dell XPS13 9343, I'm using FDE with sepreate boot and
  EFI and NVMe disk. Under high memory load, usually when launching
  additional window my display goes blank, WiFi connection is lost, I
  can only reboot and Ctrl+alt+Fn

  When I do the second I'm getting following message:
  "unexpectedly disconnected from host boot status daemon" under high memory 
load 
  Volume-Group 'ubuntu-vg' not found'
  [...]
  Please unlock disk nvme0n1op3_crypt:
  "
  Despite I enter correct password it doesn't work, seems like it lost 
connection with NVMe drive at all
