Hi,

I'm getting regular hangs after resume from suspend with the igc driver, for
an I225-V (rev 3) on an MSI Pro Z690-A, with version 5.18.11 on archlinux. A few
stable versions ago it was possible to get the network back up by removing and
reloading the igc driver, however now I get the following, and only a reboot
works (which itself hangs before actually restarting the machine, and requires
a hard reset).

Any ideas?
