[Bug 1981622] Re: mtd device must be supplied (device name is empty)

[Pablo]

Hi, i'm getting same message with Ubuntu 22.04 fresh install but only at a new Thinkpad T14 (AMD 7pro, SSD M.2) with dual boot.
Also i can not suspend SO because when wake up crash with message:

EXT4-fs error (device nvme0n1p6): __ext4_find_entry:1612: inode #170139:
comm gmain: reading directory lblock 0

and

systemd-journald[403]: Failed to write entry (9 items, 326 bytes),
ignoring: Read-only file system

Just a blackscreen with this messages over and over. So the only option
i have is to force power-off.

With the old Thinkpad T430 (I5, SSD) Ubuntu 22.04 upgraded from 20.04
everything it's fine.

Title:
  mtd device must be supplied (device name is empty)

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  After updating my 22.04 system (possibly caused by Systemd update).
  And now booting, dmesg has two errors:

  'mtd device must be supplied (device name is empty)'.

  See line 8 and 134 in the included logfile.

  The system are booting as it should though, and the system are working
  like it should no errors at all.

  Is this maybe caused by 'efi-pstore-not-cleared-on-boot.patch' in
  systemd?

  I have an EFI mounted at boot but it isn't used because I have
  installed my system in legacy BIOS mode.

  Is this maybe the culprit?

  I could ignore the message but it isn't nice though.

  Regards
