    @stephenw10 I asked ChatGPT the same question as in my previous post and after a short chat it turns out it is ZFS:

    $ zpool status -v
      pool: pfSense
     state: ONLINE
    config:
    
    	NAME        STATE     READ WRITE CKSUM
    	pfSense     ONLINE       0     0     0
    	  mmcsd0p4  ONLINE       0     0     0
    
    errors: No known data errors
    

    Is there anything else I could use to retroactively diagnose the problem? I already fed the boot log to ChatGPT to look for errors, but it didn't find anything scary. Should I share it with you and if yes, is pasting it in a post acceptable?

      Then you can run a zfs pool scrub: zpool scrub pfSense
      https://docs.netgate.com/pfsense/en/latest/troubleshooting/filesystem-check.html

      You can upload the logs here and I can look at them:

          That's just the boot log from after the outage happened.

          We need to see the system covering the event. So from at least some hours before until and including the reboot.

          You should disable the on-board audio device though. It just uses resources and does nothing in pfSense.

            @stephenw10 Thank you for looking into my issue. I uploaded system.log twice, because I messed up the first one. I guess this is what I should be looking at, right? (from /var/log).
            I think the issue happened around 17:45 (March 18). I left my computer around 17:40 and when came back pfSense was dead.

            I should disable the audio device in UEFI, right?

              Yup somewhere in the EFI/BIOS setup you should be able to disable it completely.

                Mmm, nothing really shown in the logs at all:

                If nothing is logged at reboot like that it can be a hardware issue.

                I assume you didn't see a crash report after rebooting? It doesn't look like you have SWAP configured so you wouldn't see one if it panicked.

                  @stephenw10 Thank you for your time looking into the logs. I did not see any crash reports. Do you think I should configure swap in pfSense in case this happens again?

                    You would need to re-install to do so. But that would then give you a crash report if it was the result of a kernel panic.

                      @stephenw10 Then I'm just going to stick with my current setup and see if there is anything on the console the next time this happens, if happens.
                      Thank you for your help, much appreciated!
