Hi Folks,

I recently upgraded the network to Intel X550-T2B card hoping to use my 10G home network. Initially when installed the server was on 7.3.0 i beleive and it worked (at least detected and worked for few days). And recently upgraded to latest version 7.3.2. initially the card showed up on the system and i was able to use it as my main network. recently the card disappeard from the system and i can no longer get it to work. looks like a driver problem.

anyone know if there is a fix for this ?

i think intially the system booted on onboard NIC, and i made some changes on network settings page which let me move br0 interface to the 10GB port. since the card disappeard, i can no longer open the UI using static IP assigned to the system

I am using an AsRock B560 PRO-4 motherboard with Intel 10400 CPU and the Network card is installed on PCIE1

not sure if i can pull diagnostics without UI access. attached some info about the error from card/driver.

the card was purchased from Ali Express.

Google AI suggest if i upgrade the NVM using https://www.intel.com/content/www/us/en/download/19359/non-volatile-memory-nvm-update-utility-for-intel-ethernet-adapters-550-series-windows.html, it might fix it. not sure about this yet. will anyway.

Please post the diagnostics.

Not sure if it is useful anymore.

i downloaded the Intel NVM updater and updated the NVM to latest version 3.70 and after that the card is back up again. don't know it will stay trouble free. the dmesg looks good as far as i can see. Also attched the latest diagnostics.

Hopefully it's resolved, but if it happens again, post new diags.
