e1000e eno1: Detected Hardware Unit Hang:

[Keld]

started getting this error recently.. the whole machine crashes and all containers become non-functional and unreachable.

I second this. I updated to Proxmox 8.4.1 and started receiving the server going offline. It appears it still function to some degree but the network goes down on the host. I applied this and will post back to confirm if it resolves the network hang.

root@proxmox:~# ethtool -K eno1 tx off rx off
Actual changes:
tx-checksum-ip-generic: off
tx-tcp-segmentation: off [not requested]
tx-tcp6-segmentation: off [not requested]
rx-checksum: off

Same for me, suddenly i found not access my proxmox via network or local... Luckely i was home and could restart it manually.. but now in worried that this might happen when im not at home.

Edit: 6h later, this happens again, installed via link to community script... Will see if this works better or not.

Just a thought, Sorry for being new but will this je in a fix in a coming update? Do i need to remove this script in the future?

Edit 2: almost 24h later, not got any issue yet, still running and all seems ok. No error in logs either.
