  Can't boot with Linux 5.4.0.*

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When booting into Ubuntu with Linux kernels versions 5.4.0.* (checked
  5.4.0.42 and two uncertain previous versions, something like 5.4.0.40
  and 5.4.0.38).

  The laptop stays at a black screen with the following printed
  (disclaimer: typed manually from a low quality photo of the screen---
  typos and mistakes expected):
