Core dump summary from affected machine

I have three machines with SFN5122F NICs, and on each of them, loading sfxg=
e in
FreeBSD 13.0-RELEASE causes an immediate kernel panic. This does not happen=
 on
FreeBSD 12.2-RELEASE, on which the cards work perfectly.

The machines are a dual socket Xeon X5650 machine, a quad socket E7-4870
machine (Proliant DL580 G7), and a newer Ryzen 3950X machine.=20

I loaded sfxge after boot manually using kldload.

I have generated a crash dump, which I am happy to provide in full if
requested, on the 3950X machine, as the others are active servers. The PCI =
HWID
of the card in this machine (they should all be identical cards) is [1924:0=
803]

The kernel used is the default downloaded via the mini-memstick bsdinstall =
for
13.0-RELEASE. I have made as few alterations to the system as possible
post-installation before triggering the panic.

Attached is a full dump summary. If further details are needed more
expediently, I am Ampera on #freebsd on Libera.
