[SOLVED]Network connection only works after down/up and reset

Network connection only works after down/up and reset

I need help configuring my ethernet connection, please.
I want to connect via ethernet and set a static ipv4 address.
I can configure the connection manually, or via systemd-networkd or NetworkManager
only if I manually bring the device down and up again and then re-configure
a second time.


Gateway: 10.10.10.1
DNS: 10.10.10.1
Hardware: Supermicro A2SDi-4C-HLN4F with 4x Intel X553 1GbE (ixgbe)

I want to assign the ip 10.10.10.10.

Manual configuration test:
$ ls /sys/class/net
eno1
eno2
eno3
eno4
lo
$ ip link show eno1

Add IP address 

$ ip address add 10.10.10.10/24 broadcast + dev eno1
$ ip address show

Add route 

$ ip route list

$ ip route add default via 10.10.10.1 dev eno1

I also tried NetworkManager with similar results. Doesn't work until i bring the device down and up again and restart NetworkManager.
I'm out of ideas now and need you help, please.

Re: [SOLVED]Network connection only works after down/up and reset

What's the output of...

systemctl --list-unit-files --state=enabled

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan

Re: [SOLVED]Network connection only works after down/up and reset

I assume it works when eg. using dhcpcd instead of a static IP solicitation - assuming the router supports dhcp? (Ensure to stop systemd-networkd before trying a manual connect + dhcpcd or dhclient)
Did you check the router logs about its opinion on the desired IP?

Re: [SOLVED]Network connection only works after down/up and reset

Hi seth,

thanks for the suggestion. I disabled systemd-networkd and systemd-resolved, rebooted and tried dhcpcd.
Same result: works on second try.

About the router logs. I have an asus router DSL-AC52U but couldnt find anything useful in the logs in the webinterface.
I have ssh access to the router but dont know what to look for.

EDIT: booting systemrescuecd (a gentoo linux based distro) results in: eno1 gets a dhcp lease automatically after booting.
They seem to use NetworkManager. I've already tried NetworkManager on archlinux (as stated in the first post).

Re: [SOLVED]Network connection only works after down/up and reset

You're not receiving an offer on the first try; wild guess: do you use any power saving mechanisms? (TLP, laptop-mode-tools, powertop autotuning etcetrc.)

Re: [SOLVED]Network connection only works after down/up and reset

I didnt install and activate any power saving mechanisms. Not that I know of. Its a fresh install with only a few additional packages (pkgfile, dhclient, dhcping, openssh). Also the Mainboard is new. I didnt install any other operating system.
The list of activated systemd units was posted in my second post in this thread.

I also tried 3 cables and all 4 Interfaces on the motherboard.
Ubuntu and systemrescuecd configure the network out of the box just fine.

Re: [SOLVED]Network connection only works after down/up and reset

For more poking around: which kernel in particular? Does it also happen w/ the LTS kernel?
Try to load ixgbe w/ debug=16 for more module messages to compare between the 1st and 2nd attempt.

The router should have a frontend to access the logs, http://screenshots.portforward.com/rout … al_Log.htm

Re: [SOLVED]Network connection only works after down/up and reset

I am using linux-4.16.11-1. just upgraded to linux-4.16.12-1 and no luck.

$ uname -a
Linux orion 4.16.11-1-ARCH #1 SMP PREEMPT Tue May 22 21:40:27 UTC 2018 x86_64 GNU/Linux


But I tried linux-lts 4.14.41-1-lts and it seems to work. I dont have much time at the moment, so no time to test further. (Especially Option debug=16 for ixgbe).
But I am hopeful. Thank you very much for your help. :-)

Nonetheless, I will try to further test and see if I can come up with an explanation, why the linux-lts makes it work and linux-4.16.11-1 didnt work.
Maybe I can pinpoint the version thats breaking and use git besect afterwards to identify a commit responsible.

Re: [SOLVED]Network connection only works after down/up and reset

I suspect that the problem is the configuration of the kernels >= 4.16.x

I did a git bisect run for the repository https://git.kernel.org/pub/scm/linux/ke … stable.git between the tags v4.15.15 and v4.16
To save time I compiled the kernels using 

$ make localmodconfig

as shown in https://wiki.archlinux.org/index.php/Ke … ompilation
To my surprise, they all worked.


To further test, I pulled the PKGBUILD for linux-4.16.1 from the archlinux build system
and compiled it using these variations:
a) unedited linux-4.16.1 --> does not work
b) used config from linux-4.15.15, hit [ENTER] for every additional configuration parameter --> does not work
c) used config via "make localmodconfig" --> does work


How would I further go about finding the cause? Do I need to test variants for every new or altered kernel Parameter?
I tried adding debug=16 as Parameter for ixgbe via

$ cat /etc/modprobe.d/ixgbe.conf
options ixgbe debug=16

but it doesnt show when using

$ systool -v -m ixgbe
Module = "ixgbe"

  Attributes:
    coresize            = "348160"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "0"
    srcversion          = "53C84372833B4BD66B74CAA"
    taint               = ""
    uevent              = <store method only>
    version             = "5.1.0-k"

Re: [SOLVED]Network connection only works after down/up and reset

Update: the problem only occurs when the kernel config has CONFIG_INET_ESP_OFFLOAD=m or CONFIG_INET6_ESP_OFFLOAD=m set (as it is in the linux mainline kernel package).
I did a new kernel bisection with those kernel config parameters and found that

I also found that a few days ago, someone with similar hardware reported the same bug upstream already.

And I have the phenomenon. 50 minutes after boothing, ixgbe says "detected Tx Unit hang" -> "initiating reset due to tx timeout"
