Igc driver issue

impulse200 · February 13, 2026, 7:47am

Hello.

Out of the blue after I booted up my PC one day I found that there’s no ethernet device available. I checked logs and got something like this:

sergey@win7:~$ journalctl -b | egrep -i “igc|eth|0a:00.0

What I tried up to date:

completely power off the system. i.e. pull the cord from psu, press and hold power button until link led on the eth interface went off
boot older kernels
enable wifi interface and update to the latest kernel available (6.18.9 atm)
various recipes from google like adding pcie_aspm=off or pcie_port_pm=off to kernel cmdline

Nothing of that helped. I’m at loss here. Ethernet on this PC is more stable and has more bandwidth then wifi interface. And I very much like to have eth back.

Any help would be greatly appreciated.
