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@mtdpstore.service //' /etc/systemd/system/systemd-pstore.service # systemctl daemon-reload [Impact] Due to mtdpstore not being properly configured as a pstore backend, when systemd-pstore.service tries to load the module, users get the following error in dmesg: [ 18.453473] systemd[1]: Starting Load Kernel Module mtdpstore... [ 18.462685] mtd device must be supplied (device name is empty) This is a distracting error for users trying to diagnose other system issues, especially if their system does not boot after a kernel crash and this is the only message displayed on the console. [Test Plan] * Force a kernel crash to populate /sys/fs/pstore, thus causing systemd-pstore.service to start on the subsequent boot: # echo 1 > /proc/sys/kernel/sysrq # echo 1 > /proc/sys/kernel/panic # echo c > /proc/sysrq-trigger * When the system reboots, observe the error in dmesg: # dmesg | grep mtd [Where problems could occur] If a system was relying on this pstore backend, and mtdpstore is built as a module, it is possible for systemd-pstore.service to trigger before mtdpstore is loaded, causing systemd-pstore to not copy the contents of /sys/fs/pstore. Note however that before the patched introduced as a result of bug 1978079, systemd-pstore.service would not attempt to load *any* kernel modules. [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.
