      Did someone test the traffic shaping on 2.4.1?
      I didn’t have the time to do it this week, and next week I don’t have the time either.

      it needs you guys with the problem to test, no point in me testing as I dont get the crash on 2.4 anyway.

      Its far easier for you to test than for someone to backport the driver, (note the fixes are also in the kernel rather than the driver).

      Do a config backup.
      Download 2.4.1 snapshot from pfsense servers.
      Install 2.4.1
      Restore the backup.

        but the main question is how stable is 2.4.1 coz on my box on 2.4 it doesnt crash and on this i can test but where it crashes is a client box in a remote location so if 2.4.1 isnt stable then it will be cause a lot of headache for me bringing it back to 2.4

            Afraid this is really an uphill battle and altq is pretty much dead… Not sure what's the plan in FreeBSD but this buggy mess is not maintainable by Netgate alone.

              Yes its reliant on FreeBSD upstream, pfSense may refine the code, but you entering a dangerous situation if you start making large en masse changes from the upstream product as this would need maintaining outside of upstream and be a pain on every upstream update.

              FreeBSD made a decision to not keep up with openbsd in regards to PF and ALTQ so they made the rod on their own back with that decision, the good news is that they have started to fix FreeBSD specific PF issues now and I would hope this includes ALTQ as well.

              The problem in this case there is no specific confirmed bug, just a few guys reporting crashes at high load, it needs lots of testing to dig deeper.

              My advice was on the basis I am aware of scheduler panic fixes and igb panic fixes in FreeBSD 11.1 upstream hence what I posted.

                    A quick update from my side.
                    Both ALTQ and HFSC crash on 2.4.1 as well.
                    It doesn’t have to have any load. It crashes only seconds after reboot.

                    Will try to upload the crash info tonight.

                      It is gone now yes, but before it was removed, it was updated and improved over what the version in FreeBSD is.

                        Luiz fixed it.!. ;D

                        At least after initial testing with and pushing some traffic through my queue's which seemed like a sure way to crash it before, i'm gone try and see how it holds up tomorrow :)

                            It's running for a few hours now.
                            No crash since the reboot, so this looks promising.
