Likely eDP link training issue. https://github.com/NootInc/NootedRed/issues/52

Which is why NootedRed systems should use iMac20,1. It's an iGPU, not a dGPU, why treat it differently than Intel ones?

No... that's just a template for Intel framebuffers. AMD drivers don't have any IDs...

Disable RestrictEvents and/or BlueToolFixup.

So it works without rebar?

Uhh, what exactly doesn't work? Needs more information lol

VCN support in NRed is experimental, no support if you encounter issues with it, -nredvcn. The solution is... to upgrade macOS lol.

You have duplicate SSDTs lol. SSDT-EC and SSDT-USBX make up SSDT-EC-USBX-DESKTOP. You're supposed to use SSDTs from SSDTTime: HPET, EC, USBX, PLUG + ACPI patches and nothing else. AMDTSCSync is for laptops only, and even there, only problematic ones with an unsynchronized TSC.

Known issue on macOS Big Sur with NRed, update to Monterey or later and it should be fixed. https://github.com/NootInc/NootedRed/issues/65

If the laptop has a Vega iGPU, yes.

Just update the patches and all kexts to latest release. Update should go smoothly.

Is your touchpad I2C?

You're likely running an ancient version of macOS, like 11.3.

Says who...?

What? @bigMak You might have the AMD laptop USB issue, try GenericUSBXHCI kext. Else revisit your SSDTs and ACPI patches.

PM series SSDs are very unstable and the only way to fix them is to use NVMeFix on Mojave or Catalina, the fix broke on Big Sur.

Show an image. Use SSDTs from SSDTTime: FixHPET, FakeEC Laptop, USBX, PluginType, RTCAWAC, PNLF, XOSI

Have you tried this: https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/opencore-issues.html#can-t-select-anything-in-the-picker Once you fix the keyboard, press space in the picker and select the option with (external) (dmg).

AMDRyzenCPUPowerManagement on an FX CPU? The npci boot argument is completely unrelated to graphics cards, it's used to disable kIOPCIConfiguratorPFM64 (Prefetch Memory 64) in IOPCIFamily which causes issues on AMD systems which don't support Above 4G Decoding.

Debug OC is broken on some systems, try using release. An NVRAM Reset won't fix this, it's a flaw in the OpenCore code, and NVRAM Resets should be avoided since they wear out your hardware, contrary to what SOME people who say you should do it frequently. NVRAM Resets should only be done when...
