Realtek NIC RTL8125BG driver issues

[jbobf]

Hi, despite following steps from lots of other threads here and on github I can't seem to get my NIC working. I have tried installing using the autorun.sh script directly from Realteks download site "2.5G Ethernet LINUX driver r8125 for kernel up to 6.8" [1] and following the steps in linked comment on awesometic github using dkms [2].

None of the methods have gotten my card working for me, I just get no connection from any port and error messages like the ones below is constantly being printed at the host screen.

[ 108.426301] r8125 0000:04:00.0 enp4s0: NETDEV WATCHDOG: CPU 13: transmit queue 0 timed out 6215 ms
[ 129.417799] r8125 0000:04:00.0 enp4s0: NETDEV WATCHDOG: CPU 8: transmit queue 0 timed out 6252 ms

I also got an error installing with the autorun.sh script saying: Warning: modules_install: missing 'System.map' file. Skipping depmod.
Not sure what this means, searched a little for it, someone had issues with secure boot not being set to other OS but mine already was.

root@server:/media/realtekdriver/r8125-9.013.02# bash autorun.sh

Check old driver and unload it.

Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.
Completed.


I'll put some network configs below, let me know if I can provide any other outputs for troubleshooting. I'm at my wits end here, most people in threads report success after following the steps I have but I can't get it working.

Grateful for any help.

hello,
Try that :

To check which partition is /boot with vfat format:
\~# lsblk -o +FSTYPE

To initialize ESP sync first unmount boot partition:
:\~# umount /boot/efi

Then link the vfat partiton with proxmox-boot-tool:
:\~# proxmox-boot-tool init /dev/XXXXXXXX => where XXXXXXXX is the name of vfat partiton from lsblk +FSYSTEM

Then:
:\~# mount -a

Then to update modules:
:\~# update-initramfs -u -k all

If you retry autorun.sh, it's ok ?

Hi thanks for your answer, unfortunately it did not remove the warning although the autorun.sh output changed a bit.
Connecting anything to the NIC still gives out NETDEV WATCHDOG errors.
This is what the script output:
root@server:/media/realtekdriver/r8125-9.013.02# bash autorun.sh

Check old driver and unload it.

Update on my issue, NIC still getting timeout errors and won't produce a connection but I managed to fix the warning from the autorun.sh script.
Tried this script from another dkms github for r8125 drivers (https://github.com/fibreyu/pve_realtek_r8125_dkms).

Although autorun did not get the warning my NIC still won't work, anyone have suggestions for further troubleshooting?

No sorry to say I didn't find a fix for this problem. Even tried backing up all my VMs and performing a clean install, trying to install the driver in debug mode during installation like people did in this thread.

I had no success and ended up buying a Intel NIC with 1/4 the ports for the same price. And yeah it's frustrating and very much a driver issue on some level, my Realtek NIC worked instantly when I tried it in my Windows PC.
