How to Fix Alpine-Ridge Thunderbolt not working on cold boot

This mini-guide provides a structural approach to troubleshoot and fix the issue.

Prerequisites

  • Confirm your hardware specifications (CPU, GPU, Motherboard).
  • Ensure you have a bootable recovery USB and backup your EFI.

Fix Steps

  1. Boot with -v keepsyms=1 debug=0x100 to identify the exact kernel panic.
  2. Validate your config.plist using ocvalidate.
  3. Ensure your EFI matches the Dortania guide specifications for your CPU generation.

Verification

  • Reboot and verify if the functionality is restored and stable under typical usage.

Original Question:

Hi,

I've flashed my Alpine-Ridge (v2) a few days ago. Since then, it has been working great only after a restart of macOS, because the card doesn't work on a cold boot (my UAD interface is always connected to the machine). I'm on Catalina 10.15.7 (Asus TUF-GAMING Z490)

I've tried some SSDTs but the one from HackinDROM doesn't change anything (it behave the same as there is no SSDT), and another one I found creates a kernel panic on cold boot.

Do you have any solution, please?Thanks!
