[zxc2689963]

Hello everyone, the Monterey kernel panic problem has been solved for AMD R7 5800H notebook installation. It is a great thing that the CPU can now run on 8 cores. Thank you guys very much.Thank them for discovering the problem and providing kernel patches @ExtremeX@Visual

Have you tried adding TSC_sync_margin=0 into boot-args?

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

I know but with cpus=1 it’ll book right? I just want to see if there’s a limit to that.

 

[motorbott]

Would this quirk of OC work?

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

Tried it but it didn't work

 

[zxc2689963]

Have you tried Montery 12.1, not 12.3? There was major overhaul on version 12.3 if I recollect correctly. Perhaps give a try to version 12.1.

How usable is the Legion 5 on Monterey with a single core? Usable or super laggy?

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

I'm not expecting this to do anything different or work. I've enabled DevirtualiseMmio and built a DEBUG EFI folder. Please use it to try boot and upload the log files afterwards.

This time the results were different

@zxc2689963

Question, The only way to install Monterey is via Big Sur + update, or can Monterey be installed directly with boot flag cpus=1?

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

 

[alexjaixd]

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

@zxc2689963 Just wondering have you tried 12.1 instead of 12.3.1 ? Think Monterey has made some changes from 12.3 and onwards.

 

[zxc2689963]

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

 

[Shaneee]

Unless the OpenCore team have something to test on and need to they are unlikely to help out here. Algrey may know though. I'll send him a message.

hey would you share working EFI/USB boot file for this r7?

 

[zxc2689963]

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

@zxc2689963 I just tried your EFI on my 4900h laptop, it's stuck on this memory thing booting Big Sur recovery dmg. Any ideas?

 

[Allen623329]

Some common issues to check:

1. Are you using any unnecessary Kexts in your setup, CPU power management related?
2. Have you set Kernel > Emulate > DummyPowerManagement = True
3. Have you set Kernel > Quirks > ProvideCurrentCPUInfo = True
4. Have you checked the 3 x AMD Kernel Patches are set correctly for your 8-core CPU?
   • View attachment 5978 AMD Kernel Patches for 8-core CPU - 3 x entries highlighted

Yeah, they are of the correct values

i give a shot and it just stop at verbose and the laptop goes off, what should i check in the config? and the opencore doest provide any log file

To provide the log file you need to use Debug version of Opencore plus debug versions of the Lilu, Whatevergreen, VirtualSMC & AppleALC kexts and enable the AppleDebug box under Misc in the config.plist

I had heard from two different person that they might have solved it by modding the bios and motherboard themselves, or maybe we are counting on the Opencore team.

Can you get them to elaborate on it a bit more? My legion 5 will be here tomorrow so I will be able to add to testing as well.

Use this guy's EFI and modify it slightly according to the Monterey-EFI I shared. It is not recommended to install Ventura for the time being. Wireless card and sound card are invalid
