[Bug 1817619] [NEW] Update causes 30 sec boot delay on EFI system, with NVMe and LVM

[Felipe Castillo]

Public bug reported:

This bug is similar to #1814403 which has been fixed but not for all
systems.

As mentioned in https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1814403/comments/16
I have an NVMe drive with two partitions, one is an LVM partition for the root (/), which includes /boot (except for /boot/efi). The second partition has /boot/efi.
With this configuration, GRUB keeps showing the dialog no matter what, and it's always for 30 seconds.

There are two more comments in that bug report with similar problems:

There's also a bug report for Btrfs systems, which might is not
(https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1815002), hence
this bug report.
