      Welcome to emergency mode! After logging in, type "journalctl -xb" to view
      system logs, "systemctl reboot" to reboot, "systemctl default" to try again
      to boot into default mode.
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      

       

      On boot there is external USB memory attach to system.

      Whit this behave my system enters in dead lock until keyboard press ctrl-d or someone power off the system.

       

      Why does SO enter in emergency mode?  are there way to disable it?

       

      Thanks

          Hi Ruscoff,

           

          It could be due to lack of current or an issue during the boot. I have a few questions, you are using a breakout board and not the Arduino expansion board, right? Could you specify the image version you are using? Also have you tried checking up the logs with the command journalctl –xb? Additionally if you want to change the target to boot to set up multiuser you can use the command below, but I'd suggest to check the logs first.

           

          systemctl set-default -f multi-user.target

           

          Another thing you can try is flash the board with a fresh new install of the image to see it you are getting the same behavior.

           

          Regards,
          JPMontero_Intel

            Thanks Montero,

            i'm using custom board, nothing of standard. i'm using latest SO image, (release first or second week of February) . I see this problem only with last SO relase, with the one before this, i never saw that problems.

             

            I try with journalctl -xb it show an "infinite" list of problem into kernel, next time it happen i'll post some rows.

             

            Sometimes durings boot networkd-service failed to start, systemd retry 4-5 times before enter into emergency mode. This problem is quite random, it hasn't standard behavior.

             

            Thanks

              Could you attach one of these error logs so we can check it out?

                Two automatically generated crash logs, i think it show same things:

                http://www.tecnosnet.com/images/erved

                 

                PS: I saw this, maybe it is important: my application (in the log "SAILDATA_testWifi[238]") set system DateTime during startup (in the log   Jan 21 17:18:00 Marco SAILDATA_testWifi[238]: set Time date --set="2015-04-14 06:53:22") maybe the problem is due to this.

                  JPMontero_Intel have you news about crash?

                    Hi Ruscoff,

                     

                    I believe it can be due to some of the failures that appear in the boot log, but let me investigate further into this.

                     

                    Regards,

                      Could you attach the output of the command journalctl -xb?

                        Thanks for the log I’ll check it out. In the meantime have you tried re-flashing the board with the flashall method?

                         

                        Regards,

                          At the moment i never try with flashall, because i saw this problem in two different edison so i didn't think to corruption problem. I'll try and let you know.

                           

                          By the way i can't understand why it happens because the crash isn't repetitive or systematic.

                            Ruscoff – have you tested it with a mini breakout board or an Arduino expansion board to see if it still get into emergency mode?
