25.11: Fatal trap 12 on reboot

@stephenw10
I am very grateful for your help and support!

stephenw10

No worries. I'm happy you're able to test an early dev snaphot. Finding these issues earlier makes it much easier for us.

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.

I’ve opened another thread about the Virtual IP (VIP) issue I mentioned earlier.
