I don't see the patch or dmesg log here, but can confirm that the issue still 
persists with the latest FreeBSD 13-STABLE snapshot.

devmatch_enable="NO" in /etc/rc.conf

indeed allows you to boot the device, but only as long as no PCIe device is connected.

I tested with different cards (I350-T4 with a Riser 1x to 16x cable, VL805 USB 3.0 Card) 
and ran into kernel panics every time I tried to boot. Just calling devmatch also 
results in a kernel panic.

Nevertheless, my device was running quite stable for 2 days building world, kernel and 
ports without any brake :)

      There's something wrong with rman and libdevinfo, see attached patch and dmesg.

Do you mind sharing the patch?

Btw., I assume you're using the standard IO board, right?
