kakashisensei Posted November 4, 2020 Share Posted November 4, 2020 I've been getting this warning in syslog every minute. Eth0 is always being renamed to some unique string. Nov 3 14:57:48 Tower kernel: igb 0000:04:00.0 eth0: mixed HW and IP checksum settings. Nov 3 14:57:49 Tower kernel: igb 0000:04:00.0 eth0: mixed HW and IP checksum settings. Nov 3 14:57:49 Tower kernel: eth0: renamed from veth3d8769f Nov 3 14:57:49 Tower kernel: device br0 entered promiscuous mode Nov 3 14:58:50 Tower kernel: device br0 left promiscuous mode Nov 3 14:58:50 Tower kernel: veth3d8769f: renamed from eth0 This is the iommu grps for the nics. IOMMU group 28: [8086:1533] 04:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) IOMMU group 29: [8086:1533] 05:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network Connection (rev 03) My motherboard has dual intel nics and ipmi. The ipmi will share use of a nic, but primarily defaults to the first nic. The ipmi has its own configured ip, so there are dual ips on the first nic, one for the ipmi and one for unraid. In order to pass the second nic to a VM, I added the line to flash boot up that hides that nic from being used by unraid. Any help is greatly appreciated. Thanks. Quote Link to comment

JorgeB Posted November 5, 2020 Share Posted November 5, 2020 The checksum errors stated happening with the igb Intel driver a few releases ago, they are harmless, the eth0 renamed logs are normal, they are related to the docker engine. Quote Link to comment
codefaux Posted June 9, 2021 Share Posted June 9, 2021 While I understand that they are harmless and related to the Docker engine, we're also having an nf_conntrack related crash, with the Docker engine. Some of us, at least, in another thread which the devs recently mentioned that they can't reproduce. Maybe this should be looked into instead of dismissed? What is the actual location of the misconfiguration? How would one go about setting it to conform, despite it being harmless? Is this within the reach of an experienced Linux user, or is this developer land? Kernel parameters? Module parameters? Sysctl pokes? I cannot find reference to this error that isn't an unRaid forum, and none of the ones I've found have a fix. 1 Quote Link to comment
