Panic CPU ? What the hell is that ?

Petaire · Oct 27, 2013

Hey guys.

I've just bought a brand new hackintosh. It's Z87X-UD3H with a i7 4770K and my GTX 660. Everything works like a charm, except that stupid Google Drive who keeps crashing all the time, but my big issue is with a kernel panic.

I get that message after playing few minutes on Don't starve :
panic(cpu 0 caller 0xffffff80002dc19e)

The rest is here : http://tof.canardpc.com/view/1d6c2ecd-4528-4e30-8596-4c7490d8373d.jpg

This is the config I use on MB : http://tof.canardpc.com/view/6198e7db-d24b-4cb5-b338-927768bb5629.jpg (I know there is two system definitions, I'm only using either the macmini 6,2 or the MacPro3,1, none is working and the bug is still there).

Does anybody have an idea ?

Oh and by the way, I had to set the RAM to 1600 instead of the default 1333.

So no one ?

You could try one of the new Imac system definitions , probably more suited to Haswell.
I use Imac 13.2 for my build, which is older Ivybridge board.

I think I solved my issue. It seems that this motherboard hates when you have the 4 DIMM slots used, which is kind of a pain in the wut. So now I have 16GB instead of 24… That's a bummer when you edit huge video files. I'll keep you inform if the CPU panic error comes back.

OK so no, the issue is still there. I'm gonna try with the 14,2 imac definition and I'll keep you guys informed.

Let me know if you are able to figure it out. I too thought it was the 4 dimm slots being used issue, but I still had it freeze on me. I updated the bios firmware, ssd firmware, issue was still there. Tried deleting the GPUSensor.kext because I read that it might cause freezes, but still didn't work. I don't think I tried the latest system definition so maybe that might be the fix. Let me know.

Ok so I've tried with imac14,1 and 14,2 ; and I still have that issue. It's quite a pain in the $%# ! Anybody ? Any idea ?

I've read that it may be caused by a defective HDD. I'm on a fusiondrive, so I'm gonna try with SSD only. Who knows?

Only other suggestion I have is to remove FAKESMCPlugin and FAkESMCHWmonitor, and fix permissions.
When I Built mine these caused me KP's when booting.

Okay I'm gonna try that before dislocating my fusiondrive ! I'm keeping you guys posted, and thanks by the way for your time.

edit : Do you know if you need to do something with too much RAM ? I think I've read something about that somewhere but I just can't find where…

Hey, I have the exact same problem. I wrote about it in a build thread here.
My latest post contains the information I could gather by troubleshooting but as you can see the problem is still present.

Update on random freezes:
Yesterday I checked my RAM with Memtest86+ both with all RAM modules at once as well as all modules individually. There were no errors found, but I will let a test run for at least 20 hours today to be sure there's nothing wrong with my RAM.
It seems that the ethernet kexts are NOT the problem. As mentioned before, I removed the specific kext for the ethernet port (AppleIntelE1000e.kext), but this didn't fix the problem. Afterwards I removed the IONetworkingFamily.kext, but I still got a kernel panic.
What's interesting is that this time I got more information on the panic: it was caused by the graphic drivers NVDAResman and NVDAGK100Hal.
So I switched to the internal HD 4600 and let my poor GTX 770 sit in the corner, let's see if this fixes the problem. I also put IONetworkingFamily.kext back into the system so I can enjoy some cat videos until the PC freezes or panics - I really hope it does because I don't want my GTX 770 to be the reason.

This post was just to keep people with the same problem on track, I hope this contributes to a solution.

Little summary:
What is NOT the problem: audio drivers, networking drivers
What MAY be the problem: bad graphic drivers (NVDAResman and NVDAGK100Hal), bad RAM, motherboard malfunction, maybe something with the VRAM of my GTX 770

Edit: Phew, still got a kernel panic with the HD 4600, therefore I think that it isn't caused by my GTX 770. RAM testing will run until tomorrow, when it's finished I'll report back.
