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.
