KP on 10.10.5, sandy bridge CPU. #15

I'll see if I can dig up an old Sandy Bridge processor tomorrow and test the kext myself. Hopefully to find the problem pronto. |

Thank you very much! I'd love to provide debugging info but sadly I'm not On October 21, 2016 at 18:03:01, Pike R. Alpha ([email protected])

I get a KP on kextload on a Core 2 Quad Q8200, 10.9.5 |

I'm using sandy bridge CPU e5-2670,and get a KP,either. OS 10.12.2 Mon Jan 30 00:04:05 2017 *** Panic Report *** Backtrace (CPU 4), Frame : Return Address BSD process name corresponding to current thread: kernel_task Mac OS version: Kernel version: System uptime in nanoseconds: 11900798662496 |

PS: version 1.4 works. Settings:logMSRs............................: 1 Model Specific RegitersMSR_CORE_THREAD_COUNT......(0x35) : 0x80010 CPU Ratio Info:CPU Low Frequency Mode.............: 1200 MHz CPU P-States [ 12 21 23 24 25 (26) ] But i'm still using Nullcpupowermanagement for my desktop,looking for a better way. |

use an SSDT |

BTW and for the record, I ended up switching to an i7-3770 and have it working with an SSDT created using ssdtPRgen under Sierra, so this is no longer an issue for me.

@1kevin335200, Please, do not load the kext from /S*/L*/E* or /L*/E* but load it dynamically from a terminal window. Also. What do you get from: I think that the RAPL MSR's are causing you troubles. I added checks for this in v2.3 and hope that you would be willing to give it a go. Edit: Ok. Got it. Seem like I forgot to remove MSR(0x64C) and that causes the crash on Sandy Bridge processors. AppleIntelInfo.kext v2.4 works here on a i5-2500K and i7-2500K. I even compiled it on 10.9.5 with Xcode 6 so backward compatibility is also no longer an issue. Please confirm and close this issue. Thank you. |
Because I recently installed a new GPU (Maxwell) and it was giving me various issues, I began putting a closer eye on various things in my setup and realized PM isn't working as I had expected... for whatever reason, I was only getting 2 p-states (Maybe it's the SMBIOS? Does this ACTUALLY have anything to do with the number of pstates?)
So, I downloaded and compiled your kext, fixed permissions and owner, but whenever I try to load it with kextload the computer just freezes and I need to perform a hard reboot.
I'm using an i5-2300, Max ratio set to 33 (max turbo) for all 4 cores, and the CPU is almost always at x33; only very occasionally at x16.
My SMBIOS is iMac12,2; I ask about this because I've seen other people having issues with iMac12 SMBIOSes but I'd always thought this didn't really matter much other than cosmetically. Also, using SSDT generated with ssdtPRGen, which has steps all the way from 16 to 33.
