What were you trying to do that didn't work?

Upgrade from rhel-8.4 to rhel-9.2 with a custom partition layout which has /boot in a root LVM volume. grub2 no longer includes the lvm module by default so the grub2-common generated stub /boot/efi/EFI/redhat/grub.cfg fails to boot and goes to a grub prompt.

Please provide the package NVR for which bug is seen:

grub2-common-2.06-61.el9_2.4.noarch

How reproducible:

On first upgrade from rhel8.4 -> rhel9.2, also whenever the grub2-common package is updated and the host is rebooted

Steps to reproduce

1. Start with a rhel-8 host which has a custom partition layout with /boot in an lvm volume
2. Set boot mode to UEFI
3. Upgrade to rhel-9.2 and reboot

Expected results

The host boots

Actual results

The host fails to boot and goes to a grub prompt, as the root device cannot be found because the "lvm" module isn't loaded by /boot/efi/EFI/redhat/grub.cfg
