Guys use CPUTSCSync 1.0.3 version. Its not causing panic. If you use CPUTSCSync 1.0.5 it will definitely give you kernel panic.

I have attached the EFI. You can check. Please add your own Platform details. You need to create your SSDT using the ssdttime.exe from windows and also use ssdtprgen to generate SSDT-PM from mac.

Use my EFI as a refrence

Hey, nice to know. I looked at your EFI and config.plist. There is a lot of kexts and ACPI files, that are not added to config.plist.Did you change anything special in the plist to get it working, ACPI patches, SSDTs?

Look above I have attached 2 more EFI

Same issue for my 2690V2 X79 ... i got it working sometimes with 4 cores .. but not stable. Lets hope for a fix.

If tried a fork of CpuTscSync.kext here: https://github.com/wy414012/CpuTscSync - but it wont work for my CPU. Maybe someone else will have luck.

Use CPUTscSync 1.0.3 . It will definitely work.
