Full console log

I get a kernel panic when initializing an interface for the wifi card WLE200NX (Atheros 9280?)

This happens after upgrading my opnsense installation from 24.1 (using FreeBSD 13.2-p10) to 24.7 (using FreeBSD 14.1).
I filed an issue there (https://forum.opnsense.org/index.php?topic=41816.0) and was told to tell you about this.

Some more details:

1. This is not a generic problem with the wifi card. It seems the panic only happens when the created interface is part of a network bridge.
I actually have two interfaces created using this card (different SSIDs) and the first one (WIFIG) gets created ok. When the second one (WIFIP) is created as part of a bridge, I get the kernel panic. Another user on the opnsense thread confirmed my suspicion that it is related to a bridge.

2. Disabling SMP seems to help. Another user wrote: "The kernel panic error has been fixed adding kern.smp.disabled=1 sysctl tunable value."


Here is some of what I get one the console (I attached the full output):
