Where do you set these values, under System: Settings: Tunables?

The settings may be too late if the boot takes long, maybe they could also be set under /boot/loader.conf.local, but I'm not sure.

Hi Franco,

thank you very much for your hint. Indeed, I'm setting the variables as tunables - like I described here: https://www.thomas-krenn.com/de/wiki/OPNsense_igb_EEE_Funktion_deaktivieren

Regarding setting it via configuration files you mentioned that I could try to set it in /boot/loader.conf.local
In a blog posting about network tuning in BSD - https://calomel.org/freebsd_network_tuning.html - the Intel igb EEE setting is described to be set in /etc/sysctl.conf

My questions:

  • Should I add the settings in both files to be on the safe side?
  • Is there anything else I should test right now (as the error is currently present) before I apply the settings and reboot the system?

Thanks again very much for your valuable help.

On my (meanwhile OPNsense 17.7 test system) I have now added the setting to both /boot/loader.conf.local and /etc/sysctl.conf (and rebooted the system afterwards):

I'll continue to use this setup for the next 2 weeks (I'm powering down the firewall before I leave the office, as the problem occurred only after 3-5 after boot of the firewall - at least in my tests).

By the way: With the current pfSense version I have not been able to reproduce this issue, although it's FreeBSD 10.3 base uses the same igb driver version (2.5.3) like FreeBSD 11.0 does. Are there maybe any other networking changes/tunables between FreeBSD 10.3 and 11.0 that could lead to this issue?

I'll keep you updated once I have any news on the issue.

Best regards,
Werner

Unfortunately, the problem now occurred again although I have added the settings to both /boot/loader.conf.local and /etc/sysctl.conf as described above.

As a next step to narrow down the root cause, I will continue to test with another system. The current system has 10 * Intel i211AT Gigabit LAN, the second (which I want to test now - http://www.jetwaycomputer.com/JBC385F551.html) has the following NICs:

  • 1 x Intel i219-LM PHY Gigabit LAN (iAMT 11)
  • 1 x Intel i211-AT PCI-E Gigabit LAN
  • 4 x Intel i350-AM4 PCI-E Gigabit LAN

Maybe the problem only affects the Intel i211-AT chip...

I will keep you updated. In case you have any news/ideas, just let me know.

Thanks & best regards,
Werner

As I think that the network issues might be related to some energy saving functions, I have now switched back to the JBC390F541AA-19-B system with its 10 Intel i211-AT based NICs.

I have changed the BIOS setting (BIOS Version file BAR1NA02, BIOS Date 02/25/2016) to the following settings:

  • [F3] (Load Optimized Defaults)
  • Advanced -> OS Selection -> Android (instead of the default "Windows 7")
  • Advanced -> ACPI Settings -> ACPI Sleep State -> Suspend Disabled (instead of the default "S3 (Suspend to RAM)")
  • Advanced -> CPU Configuration -> EIST -> Disabled (instead of the default "Enabled")
  • Advanced -> CPU Configuration -> Max CPU C State -> C1 (instead of the default "C7")
  • Chipset -> South Bridge -> Audio Controller -> Disabled (instead of the default "Enabled")
  • Chipset -> South Bridge -> Azalia HDMI Codec -> Disabled (instead of the default "Enabled")
  • Chipset -> South Bridge -> System State after Power Failure -> Former State (insted of the default "Always Off")

And I have set the following variables as suggested/mentioned in https://www.freebsd.org/cgi/man.cgi?query=pci&sektion=4 and https://calomel.org/freebsd_network_tuning.html

Code Select

I have also set all these variables as "tunables" in OPNsense, as some settings (e.g. "dev.igb.0.fc=0") have not set the desired value (sysctl -a reported e.g. "dev.igb.0.fc=0" - adding the variables as tunables in OPNsense fixed this).

I have added the output of "pciconf -lvbce" as an attachment (forum login needed to see it). I wanted to check the setting for Active State Power Management - ASPM (all devices show "ASPM disabled(L0s/L1)"). I have found a posting (although 5 years old), were someone suggest to disable this feature in the BIOS ("Just make sure you keep the Active State Power Management option in the Advanced Chipset Control BIOS screen at the Disabled setting (this is the default), because when I enabled this, my Intel NICs occasionally got stuck in a low power state, needing a full reset to resolve." see https://forums.freebsd.org/threads/35529/#post-195907). There is currently no option in the BIOS of the JBC390F541AA-19-B for ASPM. But as pciconf reports it as "disabled" I _think_ this should be ok.

I keep you updated whether I get the NIC issues again or not.

I did not have the impression that the settings have helped (although I have not tested over a longer period and I did not see the issue during my short tests).

Meanwhile I got feedback from the board manufacturer regarding "Active State Power Management" (ASPM) for PCIe. There is no option for this in the BIOS version BAR1NA02, but the default setting is already disable (like "pciconf -lvbce" shows it). As ASPM is not activated, it cannot be causing my issue.

I now want to narrow down whether the problem has to do with FreeBSD version 11.0. With pfSense 2.3 (FreeBSD 10.3) we have not observed the issue. As pfSense 2.4 RC is out (currently using 11.0-RELEASE-p12), I'll check whether it is running into this problem (I _think/assume_ that the problem could arise then, too).

For my test I went back to the BIOS and set the following options:

  • [F3] (Load Optimized Defaults)
  • Advanced -> OS Selection -> Android (instead of the default "Windows 7")
I have kept the default igb driver settings (so dev.igb.9.eee_disabled is set to the default "0" for all 10 NICs).

I will keep you updated once I have any new information.

Hi Werner,

Sorry to hear this is still happening, but thank you for keeping on top of it! :)

Using pfSense 2.4 RC I also got some issues after some minutes of using it. From my client laptop (connected directly to igb0 (LAN link of the firewall)) I was not able to reach the WAN network anymore. I did not break completely, I was able to reach pfSense's web interface, on the other side a SSH session, which I have opened before, broke:

A "ifconfig igb0 down" and "ifconfig igb0 up" and applying a DHCP-client configuration on my laptop (using Network Manager in Ubuntu 16.04) fixed it, but I'm not sure how long it works.

As these symptoms are not exactly the same as I had with OPNsense before, it might be that these issues could be related to pfSense 2.4 RC. But I think for this very system (JBC390F541AA-19-B) there are some networking issues with FreeBSD 11.0 which have not been there with FreeBSD 10.3.

I'll keep you updated once I have any news.
August 30, 2017, 11:31:17 AM #23
I also have a preliminary kernel for 11.1 (no HardenedBSD additions, no shared forwarding) if you want to try. There could be some fixes we are simply missing?
August 30, 2017, 11:34:17 AM #24
This would be nice, and for sure worth a try!
Can you send me some details how I could grab this Kernel and how I apply it to OPNsense?
August 30, 2017, 12:43:08 PM #25
I've sent you the details via PM.


Thanks,
Franco
August 30, 2017, 01:03:38 PM #26
Thanks a lot for the details in the PM, I'll try this as soon as 17.7.1 is out and keep you updated once I have any new findings.

I'm currently still having pfSense 2.4 RC on the system, and today in the morning I got exactly the same problem like I get with OPNsense 17.1/17.7: after some time of operation (about 1-3 minutes after boot) I run into the problem. EEE was _not_ deactivated, but as I have seen the issue on OPNsense with EEE having deactivated, too, I won't do currently any tests with EEE deactivated with pfSense 2.4 RC.

Attached you find a full bunch of logs and command output (in case it helps us to analyze the root cause of the issue).

One thing I want to show you right here - as you can see an "ifconfig igb9 down" followed by an "ifconfig igb9 up" fixes the issue:

Before I continue to test with the upcoming 17.7.1 and the preliminary Kernel, I think I'll test with pfSense 2.3 (which is based on FreeBSD 10.3) and watch out if it really works rock-solid (to have more evidence that FreeBSD 11.0 is causing the issue, while FreeBSD 10.3 brings no issues).

When I see that pfSense 2.3 indeed runs solid like expected, I'll grab all the output for analysis (especially "sysctl -a") and will compare it to the outputs that I have attached in this post. Maybe we find some settings, which differ, that then could maybe be the reason for this problem.

I will keep you updated  ;)

Since my last posting on Aug, 31st, I've been running pfSense 2.3.4 on the system, without having any issues. So I'm rather sure, that my problem has to do with FreeBSD 11.0 vs. FreeBSD 10.3. I have attached a ZIP with the logs of pfSense 2.3.4.

I have searched for differences and I have found:

  • sysctl -a shows for pfSense 2.3.4 the item "hw.igb.buf_ring_size: 4096". This item is missing on pfSense 2.4-RC. Could this be causing the issue? (UPDATE: on OPNsense 17.7.2 "hw.igb.buf_ring_size: 4096" is present - so I think this is not the root cause for my problem)
  • dmesg shows on pfSense 2.4-RC pci entries with "[GIANT-LOCKED]". pfSense 2.3.4 does not list this kind of items, see the code below. Could this be causing the issue? (UPDATE: also OPNsense 17.7.2 shows "[GIANT-LOCKED]")

Here is the code for the mentioned dmesg part:
Code Select

pfSense 2.3.4 dmesg:
  ...

Tomorrow, I will switch back to OPNsense and I will install the FreeBSD 11.1 kernel. I'll keep you updated.
September 22, 2017, 01:05:47 PM #29
I have now installed a FreeBSD 11.1 Kernel (got instruction for that from Franco via PM):

Code Select

root@OPNsense:~ # freebsd-version -k
11.1-RELEASE-p1
root@OPNsense:~ # freebsd-version -u
11.0-RELEASE-p12
root@OPNsense:~ #


Also with FreeBSD 11.1 the NICs show "GIANT-LOCKED" in the dmesg output (as they do also with FreeBSD 11.0, but not with pfSense 2.3/FreeBSD 10.3 (which does not have the issue)):

But anyway I will stay with this setup for the next days and will watch out whether the problem shows up again or not. I'll keep you updated.
