Bug#810932: EFI boot entry non-functional on NVMe system

Package: grub-efi-amd64
Version: 2.02~beta2-33
Severity: important

[Reporting as "important" because it breaks booting on this system
without manual configuration, but not RC because it may not apply to all
EFI systems, or even all EFI systems with NVMe.]

On a laptop with an NVMe disk (accessible as /dev/nvme0n1), GRUB
installs a non-functional boot entry into the EFI firmware.  GRUB
installs the following entry (read via "efibootmgr -v"):

Boot0001* debian HD(1,0,00000000000000000000000000000000,0x0,0x0)/File(\EFI\debian\grubx64.efi)

By contrast, if I use the firmware's option to browse for an EFI binary
to boot, and select \EFI\debian\grubx64.efi, that successfully boots;
after booting, the boot entries contain the following:

Boot0005* \EFI\debian\grubx64.efi PciRoot(0x0)/Pci(0x1c,0x4)/Pci(0x0,0x0)/NVMe(0x1,00-00-00-00-00-00-00-00)/HD(1,GPT,37ea4958-49da-48da-bc44-39d3f5ea6b7d,0x800,0x100000)/File(\EFI\debian\grubx64.efi)

This differs both in providing a specific NVMe device, and in using
"GPT" and a UUID for the HD rather than all zeroes.

Also, any subsequent run of "update-grub" will *remove* that entry,
making the system unbootable without again manually selecting the
bootloader by path.
