Public bug reported: 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.
