Did you see the device actually reboot when you did the nvram update? It may have soft rebooted (re-booting just the OS)?
IIRC, The eeupdate util does not work on freeBSD.

Your device is the 1st reported one of such issue.

From all the util commands you posted, the devices do appear to be there, and not sure why one or more may have moved locations on PCI bus. Maybe perhaps you have other issue with that hardware. A bad solder joint can create the gremlin, etc.

I will suggest that the update procedure include removing power for 1min after a device shutdown. Then power it back up. But noted, you should not need to do this as long as the device actually is rebooted.

Now that you mention it, all my reboots (and there have been at least 5) prior to unplugging the power cord to move the device were done with the webgui and as i was not in the same room i didn't see it rebooting. Does a reboot initiated from the gui is a hard reboot ?

From what i posted you clearly see that device with @mac ending in 32:00 is igc5 but when i had the problem it became igc4. And at this time device with @mac ending in 31:ff was not detected (it's normally igc4).
All came back in order after power reset.
I mentionned eeupdate as it was part of the firmware package i found. I first intended to use it in EFI shell which i didn't managed to do. I am still struggling to make a bootable efi usb media with my mac.

Finally i managed to flash all the devices.
I guess a reboot is not enough despite what the nvmupdate manual says.
I went to the basement and took my appliance to try a bios update.
When i plugged it the missing interface was back.

For the record i didn't managed to do the update. Making bootable usb with efi shell for flashing with a mac is really a pain in the ...
I remember having struggled for flashing an hba.
Anyway in the iso file provided with firmware there was also eeupdate utility (like nvmupdate but for efi) and the bin files for the i226v devices (type 125c version 2.32)

Yes the switch led lights on.
I initially had only 1 switch near my router and not enough free ports. So i decided to use 1 port fort lan and a lagg to 5 vlans. The first switch is 8 sfp ports switch with both fiber modules and rj45 ones. The RJ45 ones are 2,5G (to match my router)
I added another switch i had lying around but i want to replace it (unifi 48 port poe) it's hungry and noisy and only 1Gbps ports (except 2 sfp+)
i'm running opnsense 25.7.6. I think the igc5 update has been made within 25.7.5 version.

lspci : i suppose i need to install a package.

I didn't pay attention pci devices changed. So i guess after the reboot the appliance didn't list the same pci devices.

Hello,

I have a very strange issue.

My device is a generic N100 with 6 i226V.
I use 4 of them:
igc0 is wan
igc1 is Lan
igc2&3 are tied in lagg0 which is parent interface of my vlans.

igc4&5 are unused.
all i226 devices had 2.13 firmware.
I flashed igc5  with 2.32 and rebooted.
I didn't used it. I just plugged it in a switch and saw in log igc5 link state changed to up
Then i flashed igc4 and rebooted just like for igc5.
After the reboot igc5 is no more present and igc4 has the hardware address of igc5.
When i plug igc4 (as labelled on the device) nothing happens
When i plug igc5 (as labelled on the device) i see in the log :igc4: link state changed to UP

dmesg doesn't show any igc5 device and igc4 with address of the previous igc5.

i can't figure out why this would happen. When you flash the only reference to the device in the command line is the hardware address. You can't make any mistake.
After the flash a folder is created named after the hardware address. I have 2 folders as expected with the correct addressses.

Curiously in the bios i didn't anything related to hardware network devices.

What would you do in such case ?

upgrading from 25.7.5 and curiously i didn't have to apply the upgrade twice.

pkg was upgraded yesterday and don't remember having done this.

thanks.
I should be ok i have a kvm plugged in my router.

I quickly read the topic and have not a clear idea of your whole config.
does your opnsense have the same ip as your former router ? if not  did you update the trusted proxies section in home assistant configuration.yaml
did you reboot all your machines involved in these communications ?

I flashed igc5 (unused) with 2.32
Thanks to you and meyergru ( i have the exact same interface and version) it went well.
Need to test. I guess the easiest way is to assign it to LAN.

Can you flash an interface in use ? My WAN need to be tied to igc0.
If flashing 2 interfaces tied in a lagg device i suppoose the best is to flash the 2 interfaces before rebooting.

I've not flashed for now. I don't even know what firmware version i have.
For now lan drops are solved since the change of my patch cables.

I have still an issue but i don't know if it's related.
My issue is with suricata and netmap. If i enable ips on lan and vlans interfaces i have frequent connections drops due to netmap errors.
I disabled ids and ips (currently using crowdsec and testing q-feeds).

edit: apparently i have 2.13
'dmesg | grep EEPROM

I changed the patch cables and so far i had no more issues.
I try to move the cable and it seems better locked than the old one.
The switch is a chinese one (sks8300-8x). I found a new firmware.
On this switch i have several sfp+ modules some are fiber modules with lc connectors and some have RJ45 connectors.
The Lan is the one that had troubles. Speed is displayed at 2,5G
The two in lacp for vlans are displayed at 10G on the switch.

1/0/7 & 8 are down i moved these module on the unifi switch (links to other floors)

On router interfaces are ethernet 2,5G
SFP+ are on switch.

Thank for your answer.
Finally seems to be my patch cable.
Yesterday i moved my router to change a defective usb cable (for a kvm hid).
This morning i plug the new usb cable and noticed that led on the switch interface attached to lan (igc1) went off. And when i slightly move the cable it goes off. The interface are sfp+ 2,5G ethernet modules.
These patch cables are way to rigid and i guess not very good quality.
I ordered new cables for all my router interfaces.

Hello,

Yesterday i upgraded to 25.7.5.
In the evening, i was looking at a film from my plex server and experienced connections issues.
The plex server in the vlan 30. The plex player (apple tv) is in lan (igc1 interface).
I never had this before.
I found nothing in the logs that could explain that.
The link on igc1 (lan) goes down.
Could you give me a hint where to look ?

here i the log from system/general
