Thread 'I had my first "hang" today (ve 9.0.10) - eno1: Detected Hardware Unit Hang:'

*******************************
My Proxmox has been running wo. a hitch, since i installed 8.xx , about a year ago.

I had my first "Hang" today @06:36
Discovered by my inability to logon to the Proxmox web GUI.
The node was "unpingable" , and all VM's unreachable.

Just a tip, you only need to add tso off.
There's no need to turn off all others.
I've been using this on /etc/network/interfaces for over 2 years with no issues:

Code: 
post-up ethtool -K eno1 tso off
Code: 
post-up ethtool -K vmbr0 tso off

I also encountered the freezing issue, but when I disabled VLAN Aware and removed the Linux VLAN from the Proxmox network settings, the problem was resolved.

Code: 
root@Fehu:~# uname -r
6.8.12-15-pve
root@Fehu:~# lspci | grep 00:19.0
