proxmox: NIC issues with e1000e network adapters

Sun, 08 Feb 2026 00:00:00 +0000

Summary

Some Intel onboard NICs using the e1000e driver can intermittently lose network connectivity on Proxmox VE and repeatedly log errors like:

e1000e … Detected Hardware Unit Hang

This can cascade into Linux bridge ports being disabled (VM connectivity loss) and may trigger reboot/recovery automation if present.

A commonly used mitigation is to disable specific NIC offloads (especially TSO) and disable EEE (Energy Efficient Ethernet), then re-apply those settings on every boot using a systemd unit.

If you do anything admin-related on macOS, you know the drill: a random dialog pops up, you type your password, you continue… and repeat that 20 times a day.

GUI prompts (System Settings, installers, “needs your password”, …) can use Touch ID and often Apple Watch confirmation.
Terminal sudo can be upgraded to use Touch ID as well (so you don’t have two authentication experiences).

Clamshell reality check:

Touch ID for sudo only works when a Touch ID sensor is available. With the MacBook lid closed, the built-in Touch ID button isn’t usable — you’ll need an external Touch ID keyboard. Apple Watch can approve many GUI prompts, but it won’t replace the password prompt for sudo.
