Hello, long-time lurker.
I am running OPNSense 22.1.7_1 on a brand new Protectli FW2B and I'm getting a crash every 12-24 hours or so (panic string: page fault).
I'm only running an OpenVPN client which I've associated with my LAN network and it works great.

Attached are the full crash files.
Does this look like a hardware issue? This unit is a few weeks old.

Here's just the crashlog (ddb) and msgbuf.
The only hardware modification I made to the Protectli FW2B is adding a mini PCI wifi card (I have it disabled and only use it on-demand). I had it in another Haswell-based mini-PC running OPNSense 21.7 without any issues before upgrading to this new FW2B.

I do see interface errors when it's enabled in the counters and the logs do have the following error but researching this on FreeBSD forums and other places it doesn't seem to be fatal and it does work. I turn it on and use it rarely and the crashes have occurred when the interface is disabled in the UI.
(lots of these in crash logs)

It looks like I am hitting the same issue as: https://forum.opnsense.org/index.php?topic=28302.0
Folks in that thread are trying to apply the 22.7pre3 kernel based on FreeBSD 13.1 kernel via:
# opnsense-update -bkzr 22.7.pre3
# yes | opnsense-shell reboot
Before I do this, last night I removed the mini-PCI Qualcomm Atheros wifi card that I had added after I received my new Protectli FW2B as advised by Protectli support to simplify my hardware setup so I'll see how that goes.
Trawling through the FreeBSD Bugzilla this error could be a lot of things but there is at least a few yet-unsolved and recent bug report for similar crashes like this one: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256816
I don't know how to analyze the dumps however to understand and debug what might be the cause.
I'll report back here if I have any more crashes, if so I'll proceed with trying the 22.7pre3 / FBSD 13.1 kernel as suggested in the other thread.

Closing this out with a note, I've been stable for two weeks running since I removed the Qualcomm atheros wifi card.
It may or may not be related also (and perhaps my issue was transient enough to not notice it) but I also upgraded to 22.1.8_1 + 22.7b kernel+base (FreeBSD 13.1-RELEASE).
Marking this thread as fixed now.
Still getting these kinds of errors, now running 13-1-RELEASE ala 22.7.b beta and I've downgraded to 22.1.6 opnsense.

@dpeter, were you able to get this problem resolved? I'm experiencing similar kernel panics and am looking for some help.
