UAD-2 Solo PCIe Kernel Panic on Ryzen 9 5900X (Gigabyte X570S Aorus Elite AX, macOS Sonoma)

System Specs:

CPU: AMD Ryzen 9 5900X  
Motherboard: Gigabyte X570S Aorus Elite AX  
GPU: Sapphire RX 570  
RAM: 16GB G.Skill Aegis 3200MHz  
Audio Codec: Realtek ALC1220  
Ethernet: Realtek RTL8125  
macOS Version: Sonoma
Bootloader: OpenCore  
SMBIOS: iMacPro1,1  

UAD Device:  
UAD-2 Solo PCIe

---

Problem:

macOS installs and boots normally when the UAD card is not installed.

When I install the UAD-2 Solo PCIe card, macOS kernel panics during boot.

The panic backtrace shows:

com.uaudio.driver.UAD2System  
UAD2System::_ZN27com_uaudio_driver_UAD2Pcie220_configurePciDeviceEv  

This appears to happen during PCIe device configuration for the UAD card.

What I Tested:

- macOS boots normally without UAD card  
- Kernel panic occurs only when UAD card is installed  
- Tried forcing PCIe slot to GEN3  
- Tried different PCIe slots  
- Above 4G Decoding Disabled  
- Resize BAR Disabled  
- SMBIOS set to iMacPro1,1  

Windows also shows instability when the UAD card is installed.

Question:

Has anyone successfully used UAD-2 Solo PCIe on AMD Ryzen (X570 chipset)?

Is there any required PCIe patch, device property, or BIOS configuration needed to prevent this kernel panic?

EFI folder and panic screenshot attached.
