25.11: Fatal trap 12 on reboot

stephenw10

Ok are you able to try a custom debug kernel here?

If so rename the /boot/kernel folder to a backup then extract that .tgz into /boot and reboot into the new kernel.

@stephenw10 said in 25.11: Fatal trap 12 on reboot:

rename the /boot/kernel folder

You mean /boot/kernel.debug?

stephenw10

No I mean the kernel folder in boot. That tgz contains a complete replacement for that with the new debug kernel and all the modules for it.

stephenw10

So for example, assuming you uploaded the file via the GUI:

[25.11-DEVELOPMENT][admin@4860.stevew.lan]/root: mv /tmp/kernel_nd6_ifa_alloc.tgz /boot
[25.11-DEVELOPMENT][admin@4860.stevew.lan]/root: mv /boot/kernel /boot/kernel_old
[25.11-DEVELOPMENT][admin@4860.stevew.lan]/root: tar -xzf /boot/ker
[25.11-DEVELOPMENT][admin@4860.stevew.lan]/root: cd /boot
[25.11-DEVELOPMENT][admin@4860.stevew.lan]/boot: tar -xzf /boot/kernel_nd6_ifa_alloc.tgz

Then reboot and you should have:

[25.11-DEVELOPMENT][admin@4860.stevew.lan]/root: uname -a
FreeBSD 4860.stevew.lan 15.0-PRERELEASE FreeBSD 15.0-PRERELEASE #0 mjg-nd6-ifa_alloc-n256484-038e2217543a: Mon Sep 29 15:06:18 UTC 2025     root@pfsense-build-01.netgate.com:/usr/obj/usr/home/mjg/repos/FreeBSD-src/amd64.amd64/sys/pfSense-DEBUG amd64

Nice! That looks like something we can work with. Thanks!

@stephenw10
Just for your information, the secondary firewall has exactly the same dump, and that’s good, I suppose.

stephenw10

Yes it's exactly what you want to see in a crash report. If you get one.

Here is a test kernel that should have that fixed. Same procedure as before;

So far, so good, no crashes, thanks.
