After CPU upgrade, TrueNAS (often) doesn't find the network interface any more

[Steasenburger]

Hi everyone,
A few days ago I've upgraded my TrueNAS System with a new AMD Ryzen 5600 CPU (before I was using an AMD 2200G).
To do this, i had to also perform a BIOS upgrade for my ASUS B350M-A motherboard.
Everything was working well and the CPU was correctly detected.

However, when I started the system after the upgrade, TrueNAS did not came online on the network.
I attached a GPU to the system (since there is no IGPU anymore) and was surprised to see, that it booted up correctly but shows:

"The web interface could not be accessed.
Please check your network configuration."

And when choose to configure network configuration, there was simply no network interface at all that could be configured.

I googled a bit and found that you should add "if_re_load"="YES" and "if_re_name"="/boot/modules/if_re.ko" to /boot/loader.conf, which is what I did.
This seemed to do the trick even before the Upgrade to TrueNAS 13, where this is necessary to use 2.5 Gbit/s NICs (which I don't have).

I rebooted the system and the network interface came back and I could successfully connect to TrueNAS.
However, it was no permanent success. After I stopped the system again and tried to start it, it was offline again.
So right now i always have to perform a few reboots, before I can finally connect to TrueNAS.

Here is a bit debug output (with a working NIC), maybe it helps:

Anything else needed?

I am using TrueNAS-13.0-U2

Unfortunately, Realtek NICs have a poor experience reputation here - I suggest you search for RTL8111 and read up on them.

Hmm yeah i already read that they often lead to problems.
The thing is, that I haven't had any issues at all with the NIC until I upgraded my UEFI and CPU...

Do you recommend a separate network card? If yes, which one would be suitable (and preferable cheap).

From the Resource section at https://www.truenas.com/community/resources/hardware-recommendations-guide.12/

Gigabit Ethernet For Gigabit Ethernet, the recommendation is simple: Intel.

Any Intel 1GbE controller will work fine.

Intel I217/I218/I219-series The I217/218/219 series of NICs is actually just a PHY for the gigabit Ethernet hardware present in the PCH. These are basic adapters that will be fine for most users but lack certain features that may be useful in more complex environments. Note that -V models are not officially supported under FreeBSD (and thus TrueNAS), whereas the -LM models are officially supported.

Intel I210 The I210 NIC is a very popular model, close to a standalone I217 with some additional features (notably the ability to be multiplexed between host and BMC).

Intel I350 The I350 NIC is Intel’s high-end GbE model and supports high-end features such as Virtual Machine Device Queues (VMDq) and Single-Root I/O Virtualization (SR-IOV). It is available in both two- and four-port model

Thanks, i didn't know about this hardware guide yet.
Right now i am just looking for the cheapest possible network card, that should work fine, since I don't really want to replace my mainboard (and i guess that would be more expensive anyway).
Would something like this work for me: https://smile.amazon.de/dp/B09Z6P6L5X ?

Or what about this network card, which is event cheaper? https://geizhals.de/level-one-gnc-0105t-a69895.html?hloc=at&hloc=de&hloc=eu&hloc=pl&hloc=uk
Its chipset is not listed in the hardware guide, but it's also from Intel, so it could work...?
Here is the English datasheet, if you are non-German: https://gzhls.at/blob/ldb/2/0/1/2/1ad9bb8467e564db4c8d533f134cfc810067.pdf

Your second card would not fit your board since it is PCI not PCIe

Amazon.de

would be a fit for your board

 

[Steasenburger]

Great, this one is even cheaper. Thank you very much :)
