Kernel panic on Threadripper 1950X #38

Closed suntrix closed 4 years ago

suntrix commented 4 years ago

I'm using OpenCore 0.5.7 / MacPro7,1 & I got this kernel panic during boot:

Hi, this problem was caused by AICPM, not this kext, you should either disable it with NullCPUPM or the kernel patch.

I already use DummyPowerManagement

I got it to boot by shuffling kexts around & switching to iMacPro1,1.

Now my kext order is:
