[9.312] Intel 82572EI e1000e Hardware Unit Hang

BarryG
Hi,

I have rebuilt one of my firewalls, using a Z87 motherboard and an Intel 82572EI PCIe NIC as eth1/WAN.

I'm now getting a LOT of e1000e "eth1: Detected Hardware Unit Hang" messages, and the firewall stops responding on ALL interfaces including LAN.

I notice the UTM says it is disabling TSO, but that doesn't seem to be enough.

If I run
ethtool -K eth1 tso off gso off  gro off
it gets MUCH better (maybe solved).

Where should I add this to init or udev?

lspci:
01:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06)

Thanks,
Barry

    ISTM this line in  /etc/udev/rules.d/20-nic.rules should disable TSO for eth1, but I don't see any message about TSO in dmesg other than from eth0

    # e1000e: disable TSO for 82572EI (errata 7, #30669)
    SUBSYSTEM=="net", ACTION=="add", ATTRS{vendor}=="0x8086", ATTRS{device}=="0x107d", RUN+="/lib/udev/nic-disable-tso"
