Fix Intel e1000e error

Please note - you may want to validate whether the options used affect your setup.

Create a new service file.

nano /etc/systemd/system/disable-offloading.service

Paste the required information/command in the newly created service file - please change eth0 to your desired adapter.

[Unit]
Description=Disable NIC offloading
After=network.target

[Service]
Type=oneshot
ExecStart=/sbin/ethtool -K eth0 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

Load the new service file and enable on reboot.

systemctl daemon-reexec && systemctl daemon-reload && systemctl enable disable-offloading.service

Thank you so much for posting this. It corrected my Proxmox node.

Thanks you. I'm just posting the backlink to the proxmox forum thread where I found this for more context:

Thank you for posting this, was really frustrated by this issue!

Thanks, worked for me too!

I have just implemented this script and performed a reboot. Apart from systemctl status disable-offloading.service (which is showing as active), is there a way to check if the command itself has been successful at load? lol I know a big giveaway will be if Proxmox doesnt die but I would rather some way to check upfront the command has successfully been applied.

In the output of the systemctl status disable-offloading.service command, you will find the code=exited, status=0/SUCCESS which tells you the command did run successfully. Example below.

   Main PID: 880 (code=exited, status=0/SUCCESS)
        CPU: 21ms

Apr 03 09:58:56 titan systemd[1]: Finished disable-offloading.service - Disable NIC offloading.

Thanks @crypt0rr, I get the following:

root@pve2:~# systemctl status disable-offloading.service
● disable-offloading.service - Disable NIC offloading
     Loaded: loaded (/etc/systemd/system/disable-offloading.service; enabled; preset: enabled)
     Active: active (exited) since Thu 2025-05-08 09:25:20 BST; 42min ago
    Process: 941 ExecStart=/sbin/ethtool -K eno1 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off (code=exited, status=0/SUCCESS)
   Main PID: 941 (code=exited, status=0/SUCCESS)
        CPU: 21ms
root@pve2:~# 

Just wondered if there was anything else that needed to be checked but all good :) I shall see if this works in about 12 hours (my Proxmox keeps dying around 9pm every evening just in the middle of watching something on Plex)

Hm, that's unfortunate. Let us know if the solution worked for you please!

I solved it here: with post-up command

root@proxmox43:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.43/24
gateway 192.168.1.1
bridge-ports eno1
post-up /sbin/ethtool -K eno1 tx off rx off
bridge-stp off
bridge-fd 0
