First, some context: I'm hoping to find a minimal patch to Grub 2.02 to fix a boot issue on the the latest release of the NixOS distribution. Grub 2.04 fixes the issue, but some users had trouble with it, so backporting 2.04 might not be a good idea.
I'm asking this in case someone can think of something obvious to try. The symptom: When I try to boot my laptop (Dell XPS 7390 Developer Edition) with a USB stick with Grub 2.02, the laptop freezes. Specifically, when I choose the USB stick from the BIOS, or use "chainloader .../efi/boot/bootx64.efi" and then "boot" from a working Grub installation, whatever is on the screen (the Dell logo, or the commands I typed into the first Grub, respectively) stays there, a text cursor appears in the upper-left corner, and the laptop's fan eventually turns on. The question: Any idea which change between 2.02 and 2.04 might have fixed this? If anyone could suggest, say, 6 likely changes I could try patching, I'd love to try them and see if one of them fixes the issue. James
