      Do somebody else have it?
      As a result sometimes pfSense becomes

          Probably the same as that redmine, but I wouldn't worry about it unless it continues to happen on 2.5.0 once we move 2.5.0 up to FreeBSD 12-STABLE. Could be any number of problems on 12.0 causing that.

            Thanks, will see when it's ready and out.
            Now I've sequence to replicate this bug, planning to test it on 2.4.x, if I have free time in the weekend.

              It's looks like I've different issue, caused by option "Reset all states if WAN IP Address changes".
              Even having gif/IPv6 interfaces deleted this option triggers those "pf_test: ..." messages if I manipulate with WAN interface or playing with media where WAN (PPPoE) based on.
              Looks like having this option not enabled makes the system stable again.

                  If you can provide me how to set this up and can see if my environment would permit me to test it on my version of 12-STABLE. Its current and just finished rebasing it.

                  I'm currently using using a PPPOE connection and using the stf to implement ipv6 via 6RD, The stf has been modified with commits that I pulled forward from 2.4.x.

                    Actually I have multiple WANs, but I can test it in single WAN config later, to see if bug still there or not.
                    If you have WAN PPPoE, go to the System-Advanced-Networking and tick the option "Reset all states if WAN IP Address changes" reboot your firewall to make things clean and just try to re-plug the ethernet cable on PPPoE WAN port, unplug, wait for a 15 sec and put it back. If you don't see those pf_test messages in console or in system logs, system does not crashing, it's good.
                    Tested, it fails only with multiple WANs and Gateway group configured. So may be I need to test your 12-STABLE version by myself, can I download it somewhere?

                            Sad to say but I have same error on the same config. Regardless of option "Reset all states if WAN IP Address changes" enabled or not after known sequence I get those pf_test: kif == NULL, if_xname and then Fatal trap 12 a bit later.

                              @w0w did you try again after rebooting? I seen a page fault occur on my bare metal instance but not VM, but much earlier in the boot process. Second boot it doesn't occur.

                              Not likely to fix the original error however.

                                It was rebooted multiple times before I did test sequence to crash it ☺, so it is some bug. I'll wait for Netgate version, when it is out or if somebody else find something. It can be also related to ix driver, not sure, will test it also a bit later

                                  On the igb0 I have similar situation, but different message on 2.5.0-DEVELOPMENT (amd64)
                                  built on Fri Mar 13. Instead of pf_test spam I have this one...

                                      I had that fatal trap 12: page fault message happen on a test machine with 2.5.

                                      I tested mb,drive,memory,switched cpu everything tested good.

                                      I finally swapped memory even though the previous mem passed memtest for 24 hrs
                                      and the machine has been running fine since.

                                        I do not think it's memory, could be Intel card driver, I don't have any problem until I do known sequences on known configuration. Also 2.4.5 is not affected by this bug on the same hardware.

                                          If it was the network card would it not mention that in the error?

                                          It does mention what is not in memory (supervisor read data)

                                          Then the result of that is the (panic: page fault).

                                          I run dual wan PPPoE with Reset all states if WAN IP Address changes enabled
                                          and get no error's running 2.5.0.a.20200313.1633 as of today on above system.
                                          Previously in 2.5.0.a.20200312.something.

                                          It has only been running for about 12 hrs. with 1 reboot.

                                            My firewall is overall stable on 2.5.0, I can run it for a month until something triggers the fatal trap or "pf_test: kif == NULL", sometimes it crash on boot and 1 of 3 times crashing or/and this "pf_test: kif == NULL" message spamming, when there is the problem on the PPPoE ethernet port — for example ISP router is out of power or I have unplugged the cable or changed the link speed.
                                            I repeat, I do not have any of the mentioned problems on 2.4.5 version, so I think it's software problem.
