On the last line enter the following: sleep 10 & ethtool -K eno1 tso sleep 10 & ethtool -K eno1 gso off The following is untested: sudo crontab -e If there is, you may be able to add the appropriate commands to a startup script to accomplish the same result while continuing to use NetworkManager. Before I configured the bridge, I did not notice whether there was an issue with hangs and resets. I only needed to disable offloading in this specific scenario with NetworkManager disabled and using a Linux kernel bridge for QEMU/KVM. I spent several days troubleshooting this, and I hope it helps others. To add a permanent configuration change with NetworkManager disabled: sudo nano /etc/network/interfacesĪdd the following: post-up /sbin/ethtool -K eno1 tso off gso offĭetermine whether offloading is disabled (off): sudo ethtool -k eno1 The log entries for "Detected Hardware Unit Hang" and "Reset adapter unexpectedly" should cease. To test, temporarily (reset after every reboot) disable offloading: sudo ethtool -K eno1 tso off
The Intel 82579LM Gigabit Network Connection (Lewisville) defaults to offloading enabled, and disabling offloading works around the issue.Ģ: eno1: mtu 1500 qdisc fq_codel master br0 state UP group default qlen 1000ĭetermine whether offloading is enabled (on): sudo ethtool -k eno1 Various ethernet cables and switch ports were tried, but it changed nothing.

The Intel 82579LM Gigabit Network Connection (Lewisville) is using a Linux kernel bridge with NetworkManager disabled.Īpproximately every six minutes, the Intel 82579LM Gigabit Network Connection (Lewisville) reported the following: e1000e 0000:00:19.0 eno1: Detected Hardware Unit Hang:Į1000e 0000:00:19.0 eno1: Reset adapter unexpectedlyĮ1000e: eno1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Txīr0: port 1(eno1) entered forwarding state The Intel 82574L Gigabit Network Connection has been issue free.

A few months ago, I installed Linux Mint 19.1 圆4 on a system with a Supermicro X9SCM system board.
