Intel Pro/1000 VT hard lock

I seem to be getting this strange kernel panic when traffic is going from WAN<->LAN. I am using an HP T730 thin client with a Dell YT674 (Intel Pro/1000 VT) quad port NIC.
Using the pfsense shell I can pipe a download to /dev/null with no apparent errors. However, as soon as I run a speedtest on the LAN computer, pfsense hard locks (no traffic, shell freezes, hard reboot required).
The crash reporter on restart shows the following:

Any thoughts would be appreciated.
Disable all hardware off-loading if you haven't done so already.
Try increasing mbufs or reducing the queues to 1:
Unforrunately the VT is probably the only Intel card I've heard bad things about:
If that doesn't fix it then light the card on fire and buy a i350. The fewer VT cards that remain in this world the better.
This seems to be exactly the same setup you have and they ended up replacing the card:

Thanks @stephenw10. As an update to this, I replaced the Intel Pro/1000 VT to an HP NC365T and all issues have been resolved.
