Core dump summary from affected machine
I have three machines with SFN5122F NICs, and on each of them, loading sfxge 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.
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 [1924:0803]
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.
