What type of disk and wireless card are you using, there may be disk problems, check here to see if it is in the compatibility list...https://dortania.github.io/OpenCore-Install-Guide/ I had to replace the Hynix PC711 that came with my laptop BIOS Settings turn off safe boot. Close the AMD PSP

What disks do you use, possibly caused by disk incompatibility

Monterey started asking for TSC_ADJUST support, so some X79 and X99 cannot be upgraded to Monterey,Legion 5 unfortunately has the same problem, hopefully OpenCore team will add this feature in the future, may need UEFI firmware to simulate TSC_ADJUST, Let the hardware support

This EFI should be suitable for all R7 5800H laptops to install Bigsur, of course, you can also try to install Monterey, see if there is a Kernel Panic

I tried Monterey12.01,12.1, 12.2, 12.3.1, Monterey started to need TSC_ADJUST support, unfortunately R7 5800H is not supported

Legion 5 only stays at cpus=1, one CPU core runs Monterey, other AMD laptops don't know if they support TSC_ADJUST, tried loading RX6600M in BigSur modified driver, but failed, so far no one drives RX6600 in BigSur, Or send pictures to show

I start system large probability will stuck in the 'AppleNVMe Assert failed:',Probably my Samsung 970EVO hard drive is causing this problem，I can only forcibly shut down and restart many times can enter the system, I found that using GenericUSBXHCI kext can normal boot system, but the USB will...

There may be a way to boot network recovery through OpenCore, and a way to boot hard disk recovery, without upgrading to Monterey in BigSur

This time the results were different

Even with only 1 core, the speed is still very good, the special effects are full, after all, there is graphics acceleration, enough for light daily use

Tried it but it didn't work

Yes, only cpus=1 can be started, more than 1 cores cannot be started.Sorry, my English is poor

If don't use SSDT-CPUR, ll get stuck in the figure below anyway. Using CPUR will lead to Kernel Panic

Tried doesn't work

That's the wrong name. It's actually 16 threads

Tried to cancel it. It's still stuck

This is the EFI I booted to Monterey, which can only be used for booting the system, not for installation, and requires configuration modifications to install: Genericusbxhci. kext cancelled, cpus=1 cancelled, voodootscsyncamd-16cores.kext selected. This can be used to install BigSur

Thanks, but it's still stuck

The ACPI table doesn't identify CPU-SSDT, but I found it

Cputscsync.kext seems to support Intel only. It didn't work
