P9X79-E WS: macOS 11.3-12.0 freezes after boot. NICs are recognized, but there is no ethernet connection

[szydl0]

Hi!

My problem occurs only in macOS from 11.3 to 12.0 Beta 3. The 11.2 was the last one which worked fully fine.

There are two visible issues:

1. OS freezes few minutes, sometimes sooner, after boot. Mouse cursor stops in place, nothing can be done. This usually happens already in the installer/updater, but with few restarts I was able to finish installation process.

2. There is no ethernet connection from any of 2 intel bullit-in NICs. The NICs are recognized, but DHCP can not get address. With static IP they indicate connection, but nothing is loading.

I'm using latest OpenCore, kexts etc. However now I'm not able to run "RunMe" due to freezes, I enclose previous one from 11.3.1, but no update since then helped me with my problems.

System Spec:

E5-1680v2
P9X79-E WS
64GB DDR3
RTX 3090 FE
(Currently unplugged): GT710 (ASUS 4HDMI) - for GPU acceleration with stable OS

Actually I have RX560 in my HTPC, I will try this combination soon with iMacPro1,1 smbios.

Both of NICs are intel i210.

Hi!

I've found solution to my problem. Apple has changed i210 LAN driver during some update of Big Sur. New driver works well with mac ethernet, but is not working with i210 on my motherboard. To solve this, you need to force loading old driver version via added kext to OpenCore. Details in the link below:

Edit: I've stayed on 11.6.3, since other users are reporting Monterey is not working again.
@MaLd0n, do you know this issue, and if can it be solved for Monterey?
