What is your CPU's model?

i9 13900H ES

What is your GPU's model?

VASTARMOR Radeon™ RX 6750 GRE 10GB Alloy

Please describe the behaviour in detail.

The build I was using was an engineering sample of the 13900H, which has a known history of working with macOS. The reference EFI I used was from:

• https://github.com/hackintosh-club/TianBang-13900H-ES-ITX-OpenCore
• https://github.com/igeekbb/TianBang-13900H-ES-ITX-OpenCore

What I've done on both repositories:

1. Removed WhateverGreen
2. Added NootRX from https://chefkissinc.github.io/applehax/nootrx/
3. Ran OC Clean Snapshot with ProperTree
4. Ran macOS Installer

When I tried to boot, the kernel panicked with mp_kdp_enter() timed-out on CPU 1. Some initial research suggested this might be GPU related, so I'm seeing if I can get any luck here. Many thanks.

What should've happened instead?

Should be able to install Mac OS without any panic

If applicable, attach the .gpuRestart, .panic, etc file related to this issue.

I don't have the build at hand, so I had to extract logs from a video. Sorry for the inconvenience. I will be able to repeat the panic and provide the log when I have the build available.
