Intel I225-V (Stepping B3, SLNMH) is not working #9403

The device can not be loaded with errors:

From this issue in Gentoo, this error is from Linux kernel modules. Also, this issue was fixed in Linux 5.15.x, which means either upgrading kernel sources or backporting fixes from newer kernel sources can handle this issue.

Borromini commented 2 years ago

Did you try backporting the 5.15 driver to see if it works?

jellybean13 commented 2 years ago

I attempted to backport kernel module, but I failed with compilation error.

After applying patches from Linux Ubuntu 20.04.x HWE kernel (linux 5.11.22), it works.

Using patches: Kernel patches for igc: Backport igc drivers from Linux Ubuntu 20.04.x HWE kernel (linux 5.11.22) to OpenWrt 21.02 SNAPSHOT (currently Linux 5.4.182). Makefile patches: Fix missing dependencies.

@jellybean13 Have you tested that adapter as a DHCP client yet, by chance? I am having issues on an i226-V with OpenMPTCProuter and someone else just jumped in with the same problem on an i225-V b3. Have a peek at https://github.com/Ysurac/openmptcprouter/issues/2548 if interested.

See https://github.com/Ysurac/openmptcprouter/issues/3005 for what I believe is the cause of DHCP instability here. I found a fix/work-around for anyone interested in this.
