Thanks. I looked at the sched_prim.c file in the XNU Kernel source code (nice of Apple to let us know exactly where to search) and found that it's related to the TSC (Time Stamp Counter) Syncronization of the CPU cores. The section of the code which gives the panic is: https://github.com/apple-oss-distributions/xnu/blob/xnu-8020.140.41/osfmk/kern/sched_prim.c#L2836
Unfortunately Apple didn't update the XNU Source Code for macOS 12.6 yet, but I still managed to find the place where it calls the panic.
Image 1 is the code of XNU that panics if the time between cores does not match (not syncronized properly).

As seen when comparing the Big Sur and Monterey code (Image 2), Big Sur...

I use this EFI "https://github.com/ExtremeXT/Lenovo_Legion_5_Hackintosh" and cannot install online using the recovery tool

With Macos 13.3 EFI can be installed over the Internet

Can you give me another EFI for MacOS 12? Thank you
