[Bug 1578141] Re: Predictable interface names partially broken with igb driver

Wed Aug 8 05:57:13 UTC 2018

Just talked to a SuperMicro tech agent and has sent me a non released
BIOS update for the X9DRI-4LNF motherboard, which fixes Spectre and
several other fixes, including the enumeration problem of the ethernet
jacks of this board.

This BIOS update is v3.3 and dated from May 2018, so pretty recent, but
as the board is EOL there won't be any further updates and this one will
be the most up to date.

You can find the BIOS update file here:
https://drive.google.com/open?id=1PfWZXd-0DWuJ6MJh4OneeHdD1FLFXmx8

In case you don't trust me, please ask the SM tech guy to send you the
latest BIOS update, in my case it was "x9dr3p8.523.zip"

Title:
  Predictable interface names partially broken with igb driver

Status in linux package in Ubuntu:
  Confirmed
Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Note: I'm not sure whether this is really a kernel bug or something
  within systemd/udev, please advise how to further debug.

  On a system with two GE ports, instead of getting named eno1 and eno2,
  I am getting eno1 and renameN. Where N starts at 3 and increases by 2
  on every iteration of doing "rmmod igb;modprobe igb". The
  corresponding lines in dmesg look like this:

  [    2.748429] igb 0000:07:00.0: added PHC on eth0
  [    2.748431] igb 0000:07:00.0: Intel(R) Gigabit Ethernet Network Connection
  [    2.748433] igb 0000:07:00.0: eth0: (PCIe:5.0Gb/s:Width x4) 00:25:90:d7:60:8e
  [    2.748505] igb 0000:07:00.0: eth0: PBA No: 106100-000
  [    2.748506] igb 0000:07:00.0: Using MSI-X interrupts. 8 rx queue(s), 8 tx queue(s)
  [    2.802555] igb 0000:07:00.1: added PHC on eth1
  [    2.802557] igb 0000:07:00.1: Intel(R) Gigabit Ethernet Network Connection
  [    2.802559] igb 0000:07:00.1: eth1: (PCIe:5.0Gb/s:Width x4) 00:25:90:d7:60:8f
  [    2.802631] igb 0000:07:00.1: eth1: PBA No: 106100-000
  [    2.802632] igb 0000:07:00.1: Using MSI-X interrupts. 8 rx queue(s), 8 tx queue(s)
  [    2.803618] igb 0000:07:00.0 eno1: renamed from eth0
  [    2.833208] igb 0000:07:00.1 rename3: renamed from eth1

  What is even worse: Sometimes the naming changes and the second
  interface ends up as eno1 while the first interface is named renameN
  with an even N. The bad thing about this version is that when it
  happens while the installer is running, the installer will setup
  "rename2" as the primary network interface, which works fine for the
  installation itself, but after installation is finished and the first
  boot of the installed system happens, that interface will be gone,
  leaving the system without network connectivity.
