Thunderbolt 3 No Devices about gigabyte-z590i-vision-d-11900k

So I tested more and more and can't get my head around this not working. Not only no ethernet but display support via Dock is also not working.

1. I checked my DMAR (see below) - there's no restricted regions so I guess I don't need patches.
2. VT-d is on. No issues with Bluetooth or ethernet either

3. Running pretty much the same config as here now. Tried Ethernet patches on or off no difference
4. Tried the Hotplut SSDT on or off. No change.

@SchmockLord Did you had an TB Dock (with Ethernet) running in any of your tests with this setup?

Just for fun I tried booting from an USB made from this exact Repo config. Just changed the UIDs and switched USB ports. Same issues :(

What are the chances that my dock has issues with just this TB controller and not the other Mac?

[max3-2]

Alright now here's an update:

So this took a while but I at least tracked it down. It is the AppleIGC.kext which I had as a replacement for the i225 compatibility in upcoming Sonoma. As soon as this in there, TB ethernet breaks. TB ethernet also uses the same driver as onboard ethernet (but onboard works with AppleIGC 😕 )

I still don't get my dock as TB device but now I get ethernet on TB bus, see image attached.

I'll keep this unsolved / running if anyone has ideas or experience why the dock does not show up as TB device but the rest is working (and ethernet is mapped ob TB, too...). Let my ask again @SchmockLord did you try the new 0.9.5 tag with AppleIGC on a TB dock, preferably stating which dock? Thanks! (and again thanks for the great working baseline here!)
