Comment 1 for bug 1939988

This issue affects me as well on the HP Elite Dragonfly G2. It's really awful, I can't even start the boot process on a Ubuntu live installer. It doesn't seem to matter how I format the USB drive either. I have Fedora 34 installed but I cannot boot Ubuntu 20.04, 20.10, 21.04, or 21.10 at all. When selecting an entry with GRUB on a Ubuntu live key, I just get a black screen with a blinking white cursor at the top. What could be the problem? I regret buying this machine immensely, it has issues already with charging and wifi. It seems that the firmware won't allow us to boot Ubuntu or Debian or really any non-Fedora/RHEL distribution. On Parted Magic, I get an "out of memory" error immediately and cannot boot the image. I think this is also what is happening with the Ubuntu live image. Is the firmware reporting available memory incorrectly when attempting to boot or blocking initramfs over a certain size? Is it possible to fix this? Honestly I'm so upset at HP for introducing firmware bugs like this. No one in their right mind would design system firmware like this to prevent the booting of Linux.
