mp_kdp_enter() timed-out on cpu 4, NMI-ing

[Lazarevic]

Hello, I successfully installed macOS Monterey, but the system crashes when I use Discord or when I open League of Legends. I keep getting a "Panic CPU" issue. If anyone knows how to solve it, I would be really grateful

The Panic is actually due to the AMD GPU.

Remove AMDRyzenCPUPowerManagement.kext, SMCAMDProcessor.kext, and SATA-unsupported.kext

Also, remove unfairgva=1 boot arg.

I will try and let you know results, thanks!

Hello, I removed the kexts you mentioned and the boot argument, so the last error disappeared. However, it still causes a panic issue, but now with a different kext exception

Kernel Extensions in backtrace:
com.apple.kec.pthread​

Attach the revised EFI to check!

Have you mapped the USB ports on your own?

Is your BIOS up to date? Does it has 4G Decoding option?

Also, what boot drive are you using to boot macOS?

Yes, the ports are mapped correctly as far as I understand. I also updated the BIOS to the latest version yesterday because I thought the issue might be related to that. I have tried both enabling and disabling 4G Decoding, but the problem persists. Once the game loads, the system seems to go into sleep mode, and the GPU fans ramp up to 100%. For reference, the boot drive is a Kingston SA400S37120G

Hello, I managed to fix the last issue, and the Metal API now works as intended. I can get into a League of Legends game, but the panic issue still occurs randomly after a certain period of time. Attached are the crash message and the updated EFI. Thank you for helping me resolve these issues

Use 4G Decoding and remove npci flags.
