Details:

After upgrading from fedora 33 (grub 2.04-31.fc33) to fedora 34 (grub
2.06-2.fc34) there is a problem with booting.
even before grub menu appears 2 pages with errors are shown

> grub-core kern disk_common.c:47 attempt to read or write outside of disk
'vgDATA/data'

it stops booting and waits with "--- more ---" for confirmation.
When SPACE is pressed it prints second page of (same) errors and then it
displays boot menu and then boots normally.

It is annoying for unattended reboots.


after downgrading to grub 2.04 there is no problem.


my system is UEFI
