      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.

        Hello all,

        As was announced 2.5 to be soon mainstreamed, I jumped onto the dev branch.

        15 minutes after successful upgrade net went down, I couldnt ping or load pfsense web.
        Error streaming on screen without stop was

        igb1: TX(2) desc avail = 1024, pidx = 0

        Running 2.5.0.a.20200330.1049 (latest x64)
        Potential Solution based on power settings posted here? Not sure how to issue these commands. (from terminal at firewall, thru web, ssh...???)
        https://forum.netgate.com/topic/149643/igbx-bug-tx-1-desc-avail-no-carrier

        Bug report mentioned elsewhere here:
        https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239240

        Had been running stable until now and never had a single issue.
        Only way to get the firewall working (tried ifconfig up down, bridge up down, reset web config, etc) was to reboot the firewall. Has been working for over 50 minutes now without issue...

        Heres the logs at time of event.

          I am waiting for 2.5.0 based on STABLE. Expected to be soon. I hope that it will be released before the end of the world. ☺

            Good news is it hasnt failed on me again since the one time 15m after original upgrade.

            So... scary start, but stable for nearly 24hours now.

            Hopefully that release is SOON.

              Re-tested on the latest build
              2.5.0-DEVELOPMENT (amd64)
              built on Fri Apr 03 19:36:42 EDT 2020
              FreeBSD 12.0-RELEASE-p10
              Don't know what exactly was merged/patched, whatever else, but I can not crash my system anymore with my test sequence. I'll check later what changes are made on github.

                Hmm... looks like this thing came back, after I've configured CARP and started to play with PPPoE on secondary firewall and re-plugged main ethernet cable that cames from ISP (PPPoE).

                Crash report begins.  Anonymous machine information:

                  Got those topic messages on backup firewall also, when experimented with PPPoE (same link)

                      I've played around a bit and the result is that 2.4.5-RELEASE is still not affected, and 2.5 is crashing not every time but mostly, when I issue 'killall mpd5' or even 'rc.linkup stop wan'
                      The configuration is the same. PPPoE as WAN, DHCP as WAN2, no IPv6, only failover is configured. PPPoE as tier1 and DHCP as tier2.
                      I don't think that unbound is the real cause of crash... just because I've tried to stop unbound service and repeat the sequence (multiple times disconnected and connected WAN port cable) and got another dump. crash00.txt

                      https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234296 looks very similar.

                        Do we have patch provided in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234296 enabled on pfSense latest 2.5 version? I mean https://svnweb.freebsd.org/base?view=revision&revision=343787

                          If it was marked fixed in 12.0-RELEASE then yes, that would be in 2.5.0. 2.5.0 snapshots are on 12.1-STABLE now, so well past that point.

                              Nothing I'm aware of for that, I'm afraid.

                                What do you think, сould this fatal trap be due to the radix_mpath option enabled in the kernel?
                                Any chances to get some snapshot with this option disabled?

                                  It's possible. There are other problems with RADIX_MPATH as well but I'm not sure if we're going to look into fixing them or back that out.
