          Reinstalled everything on the 6100 and presuming you guys are running more 23.09d than anything else, I pushed it on to the latest dev load. I'll run 23.05.1 on the other device for now, so much swapping around today. Probably missed something along the way.

          Anyway, partitioned for a 4 GB Swap - hopefully that will be spacious enough for you:

          [23.09-BETA]/root: 
          

          I should get some quiet WAN time tomorrow to do interface testing and hopefully achieve a kernel dump. No doubt it will be more intermittent than usual, just to be difficult.

          I'll remember to run your script too:

          script kdb.enter.default=capture on; bt; show registers; show pcpu; capture off; dump; reset

            Excellent, that looks good. Let's hope it reveals some useful data. Thanks.

              You can try manually triggering a panic to make sure it catches a coredump. Run: sysctl debug.kdb.panic=1

                Sorry Steve, this proved to be beyond me. I guess I will have to wait for the GUI button to be implemented or for a genuine idiot proof step-by-step guide to be written as this has eaten through way too many hours over too many days.

                I think I hit the assumed-knowledge barrier too often, with steps given, only to be belatedly added to with instructions like 'using console mode' or 'use kernel debug mode option 6' or 'did you edit some .conf file' or 'follow 'x' thread' or 'install 'x' package but only by method 'y'.

                So what did work:

                • got console working from macOS (mislabeled as GNU screen in pfSense docs)
                • got the swap partition size changed via console
                • fresh install
                • installed pfSense-kernel-debug-pfSense pkg from the GUI command line
                • ran kdb.enter.default=capture on; (etc) script from regular CLI
                • reboots (many)
                • kdb.enter.default=capture shown under /root
                • reboot into kernel debug mode via console (option 6 etc)
                • trigger panic via CLI using sysctl debug.kdb.panic=1
                • console scrolls through something that looks like a core dump...
                • crash report in /var/crash with info and text dump files
                • no core dump offered in the GUI
                • no core dump file found in /var/crash

                Clearly I am typing with a little frustration (sorry about that) but perhaps you can spot something useful in the above.

                  I'm sorry. Yes it will be much better when there's a gui option.

                  You shouldn't need to add the debug kernel just to get the coredump.

                  The important steps are:

                  1. Make sure you have enough SWAP space (you do.
                  2. Edit /etc/pfSense-ddb.conf so it contains the different default line like:
                  # $FreeBSD$
                  #
                  #  This file is read when going to multi-user and its contents piped thru
                  #  ``ddb'' to define debugging scripts.
                  #
                  # see ``man 4 ddb'' and ``man 8 ddb'' for details.
                  #
                  
                  script lockinfo=show locks; show alllocks; show lockedvnods
                  script pfs=bt ; show registers ; show pcpu ; run lockinfo ; acttrace ; ps ; alltrace
                  
                  # kdb.enter.panic       panic(9) was called.
                  #script kdb.enter.default=textdump set; capture on; run pfs ; capture off; textdump dump; reset
                  script kdb.enter.default=capture on; bt; show registers; show pcpu; capture off; dump; reset
                  
                  # kdb.enter.witness	witness(4) detected a locking error.
                  script kdb.enter.witness=run lockinfo
                  
                  1. Reboot.
                  2. (Optionally) Run sysctl debug.kdb.panic=1 to test the setup. You should see it writing out the coredump to swap in the console after all the backtraces scroll past.

                  Steve

                          Looks fine to me. Reboot to apply it and then try a test panic.

                            I'll be brave when she is elsewhere.

                                      TVM.
                                      I just used the GUI to command the WAN connection down and up again to trigger the panic. Give me a shout if you need a repeat or a different method.

                                        More can't hurt!

                                        Are you able to get the backtrace from the console for that? Just to confirm it's the same crash. I'm pretty sure it is though.

                                          I've since cleared the file and switched devices (to check that the qat_200xx revision was in place for the D-1736NT). It did look the same though.
