Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Hi both.

If it is of any use, the latest Big Sur 11.4 release does have support for the i225-V LAN chip BUT only the version 2 (IIRC) chipset, there is also a version "3" which is not yet fully compatible. I'm not 100% sure what the problem or difference is, but it is, sadly, real.

Big Sur 11.5 beta 3 allows both Ethernet ports to connect. We simply set the i225-V’s device-ID to F3158680 to trigger the native driver. But in Monterey the port does not establish a connection. Hence I suspect something is amiss in Monterey.

The i225-V actually works well for me in 11.4 Big Sur but not in Monterey, but then again also to having the kext I also have the device properties setup. I had to change the hardware setup in network to manual and not leave it in automatic else I was getting reboots.

That may be true - and may be the limit of my knowledge! - but it is certain there are two versions of the i225-V in circulation, one of which was native to Big Sur 11.4 - finally. They both have the same device-ID. As for Monterey, that is a pool of sharks I haven't yet dipped my toes into!

Okay. Maybe the support for the i225-V version 2 was only a temporary measure by Apple. I'm sorry to say I haven't installed Monterey yet as my Internet connection is too slow for such a download just now.

Just my little contribution with Monterey...
I used modified EFI as recommended by @CaseySJ
- i225-V not working (not a real problem so far)
- A lot of random KP without any clue (upgrade on duplicated Big Sur on another HD)
- more annoying is dual display not working with 2 DP monitors. I need to plug with one DP and one HDMI to get both screens working.
Hope it helps !

The random kernel panics may be due to fakepciid kexts. Please ensure to Disable for Monterey.

Are you using FakePCIID on the Z490 Vision D?

Nope, they've been removed.

Guys, I've just applied Bider's fix, and apparently my I-225V is back in 11.4 and this time with no crashing!

This is what he suggested:

1. Disable FakePCIID.kext and FakePCDID_Intel_i225-V.kext in config.plist,
2. remove everything concerning i225 in DeviceProperties/Add/PciRoot...
3. add "dk.e1000=0" (without quotes) to boot-args.

Couple of questions:

• Does this boot argument reduce the port’s speed to 1Gbps?
• Does the port connect and work in Monterey?

1) It doesn’t seem like it

2) I haven’t tried Monterey with it yet but will do later
