GRUB2 git master (d454509bb866d4eaefbb558d94dd0ef0228830eb),
EFI x86-64 system with NVMe drive (m.2 ssd).

GRUB2 can be started by EFI, but it does not see any drives, other than proc:

grub> ls

I'm attaching EFI Shell "dh -d" output as dh.txt.

It's installed to disk this way:

grub-install --efi-directory=/boot/efi --no-nvram --target=x86_64-efi
--boot-directory=/boot/efi --compress=xz --themes="breeze" --modules="efi_gop
linux lsefi boot bitmap bitmap_scale blocklist bufio cat chain cpio ehci elf
ext2 fat file font fshelp gfxmenu gfxterm gfxterm_background gfxterm_menu halt
help jpeg keylayouts loadenv ls multiboot multiboot2 part_gpt part_msdos png
progress read reboot relocator search search_fs_file search_fs_uuid
search_label sleep terminal terminfo usb usb_keyboard usbms xzio video
video_colors video_fb videoinfo datetime disk diskfilter eval extcmd
configfile echo true random regexp videotest terminal terminfo probe procfs
loadenv" /dev/nvme0n1p2

/boot/efi is /dev/nvme0n1p2, which is the ESP.

loading modules does work, i.e. insmod efi_gop and starting a gfxterm does
work fine.
