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

Well, Proxmox worked all through last night - no failures since adding and activtaing this script. So thats a win :)
I will report back in a few days time just to update but so far, it is looking promising so thank you @crypt0rr

Applied this "fix" 8 days ago after a couple of weeks of random freezing and it's worked a treat ever since. Thanks!

Well sadly Proxmox died again today. That’s 3 days without keeling over. I have looked at the system log from Proxmox UI but can’t see an error so not sure if that was related to nic issue or not. When I stopped responding I tried removing the network cable as I have seen others say that worked for them but unfortunately it didn’t help me

Thank you for this fix ... my NUC seems to have stabilised :-) I have created a PR for a Helper Script - community-scripts/ProxmoxVED#310

Hopefully this is accepted and will help others.

Thank you again, for the fix!

@rcastley Very interested in this helper script. I see in your link that the PR was accepted, where can I find the script link to try it in my environment?

@crypt0rr I tried your script, and the verification command, but I got a failure response. I wonder what I did wrong?

You probably need to edit the eth0 for the identity of your specific network card - in my case it was eno2

Indeed that was it. I haven't done something like this before so I had to search how to do this. For anyone who might be in a similar position, I used ip -a and found eno1 in the list.

Thank you so much for creating this, I ran your command and it worked perfectly.

Just confirming that this script worked perfectly for me too!
