Title:
  GRUB2 can't boot Linux on HP Dragonfly G2

Status in grub2 package in Ubuntu:
  Confirmed

Bug description:
  Hello!

  On HP Dragonfly G2 GRUB2 can not boot Linux. This issue is not
  reproducible with rEFInd or Fedora's GRUB2 (that launch vmlinuz as efi
  executable) but reproducible with Ubuntu 20.04.1, 21.04 and 21.10.

  After selection kernel in GRUB2 list there is just black screen, also
  reading from flash stop right there (judging by led on flash drive).
  Removing quiet splash, adding loglevel=10 and/or earlycon=efifb
  doesn't change anything, so it's really seems like kernel can not even
  start boot process.
