Title:
  Unable to boot after upgrade to 18.04 (only works with 16.04 kernel)

Status in systemd package in Ubuntu:
  New

Bug description:
  I upgraded from 16.04 my ASUS X201E laptop to 18.04, but now I can only boot with the 16.04 kernel (4.4.0.x), I can't seem to boot with the 4.15 kernel (I tried 4.14 & 4.16 as well, to no avail).
  Booting with the 4.4 kernel leads to the login screen and everything works OK, while booting with the 4.15 kernel remains stalled on the Ubuntu startup screen with dots, ESC shows traces stuck? on "Reached target Network is Online"
  I can successfully boot the 18.04 desktop image though, so I am assuming the issue comes from configuration files and not from the kernel itself. Any help would be highly appreciated !
