Could you try this SSDT already adapted to your system ? .. with your previous working modified Firmware (Gigabyte)

WOW!!

I'll adapt and apply it to my Z390 Designare...

Is Method MTD1 defined in your DSDT or in one of the SSDTs?

So the corrected file has corrected much. All ports on the dock are now working, and Acacias TB drive working directly and through dock. Trying sleep now.

Thunderbolt and USB-C devices still hot plug and work, but system wakes up about 2 seconds after sleep and then reboots. Oops!

Let me try cold start next and then sleep without any devices connected.

Same behavior with sleep. Also, still hangs on reboot when TB device is plugged in. Will not post. Also, UltraFine monitor is recognized in the bus, but does not activate.

No idea for now, except compare thunderbolt LOG data around Sleep state. You have my LOG file.

I will try moving this card on MSI Z490 and report back of Sleep state.

No sleep issue on MSI Z490.

I wanted to see if switching to IOThunderboltSwitchType3 might help, but (a) this breaks hot plug and (b) sleep problem persists. The modified Patch 2 is shown below, which is here just for record keeping purposes.

Patch 2:

• identifier: com.apple.iokit.IOThunderboltFamily
• comment: IOThunderboltFamily patch SwitchOS to SwitchType3 (Sonoma 14.5+)
• find: 4889DFE8 F55F0500
• replace: 4889DFE8 FDE70A00
• min kernel: 23.0.0
• count: 1

I'll check Thunderbolt logs next.
