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

[Nick Rosbrook]

Richard - I edited my above comment to clarify. That workaround is not
an attempt to fix boot on any systems.

To anyone that is experiencing boot issues, please open a separate bug
with your journal logs and dmesg logs. The "mtd device must be supplied
(device name is empty)" error is not the cause of your boot issues, and
should be ignored. The reason you all are seeing this error message is
that `systemd-pstore.service` is trying to recover kernel crash data
from `/sys/fs/pstore` *after* a kernel crash. It happens that the
mtdpstore module cannot be loaded, but systemd-pstore.service (and the
rest of the system) will happily move along without it.

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
