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

[Nick Rosbrook]

** Description changed:

+ [WORKAROUND]
+ 
+ This will NOT fix a system that is not booting, because the "mtd device
+ must be supplied (device name is empty)" message is not the cause of
+ failed boots. This work around is only for those who are annoyed by the
+ error message, but are otherwise not experiencing any issues.
+ 
+ If you are not able to boot your system, but you see this error message,
+ please open a separate bug with your journalctl and dmesg logs.
+ 
+ # cp /{lib,etc}/systemd/system/systemd-pstore.service
+ # sed -i 's/modprobe at mtdpstore.service //' /etc/systemd/system/systemd-pstore.service
+ # systemctl daemon-reload
+ 
+ [Original 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
