[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

    Thanks. I do have a Broadcom PCIe NIC, but it's incompatible with this motherboard for some reason (and Gigabyte isn't interested in fixing it).

    It is behaving much better after I manually disabled TSO (the udev script isn't doing it for this NIC).

    I did get one more reset though, although it is a different error message:
    [42706.839176] e1000e 0000:01:00.0 eth0: Reset adapter unexpectedly
    [42715.379607] e1000e: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: Rx/Tx
    [42715.379720] e1000e 0000:01:00.0 eth0: Link Speed was downgraded by SmartSpeed

    Hi, I'm still seeing some resets in 9.355 and am wondering if there has been any progress from Intel?

    [ 1823.540584] ---[ end trace 3d58c669c68d6b0a ]---
    [ 1823.540590] e1000e 0000:01:00.0 eth1: Reset adapter unexpectedly
    [ 1832.204945] e1000e: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: Rx/Tx
    [ 1832.205058] e1000e 0000:01:00.0 eth1: Link Speed was downgraded by SmartSpeed


    ETH1 is Intel 82572EI PCIe NIC

    Thanks,
