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

[buswedg]

Same problem here on 22.04 z370 system, however it is also preventing my
from booting into the system. It definitely has something to do with a
recent update. I just tried a fresh install and after rebooting from
updates, I saw the error. I'm on a SSD and running UEFI, which based on
Google results, seems to be more commonly associated with those that are
unable to get past the boot sequence.

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
