Lenovo Z70-80 Kernel Panic

[beesenpai]

Hi all. Sort of new to hackintoshing. Currently trying to do my laptop, a Lenovo Z70-80. Upon trying to boot the installer, I get a kernel panic:

panic(cpu 2 caller 0xffffff7f857c3af0): assertmsg@/Library/Caches/com.apple.xbs/Sources/GPUDriversIntel/GPUDriversIntel-10.25.17/Common/IONDRV/Intel/BDW/AppleIntelFramebuffer/AppleIntelController.cpp:21427

I have uploaded my clover plist. My kexts and drivers:

/EFI/CLOVER/drivers64uefi:
EmuVariableUefi-64.efi
HFSPlus.efi
OsxAptioFixDrv-64.efi
OsxFatBinaryDrv-64.efi

/EFI/CLOVER/kexts/Other:
FakeSMC.kext
VoodooPS2Controller.kext

I assume that the problem lies with NVRAM allocation but I'm not sure how to go about fixing it. I have not modified my BIOS' default allocation but my plist (that came from RehabMan's repo) fixed my initial OsxAptio errors so I'm not sure what I should do next.

Any help is appreciated, thanks a lot

Your panic is due to incorrect DVMT-prealloc.
It is covered in the main Clover laptop guide.

Follow the Clover guide linked from the FAQ.
http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html

Although you should read the FAQ for an overview of issues, the Clover guide is linked from the first question: "Q. Where do I start?", just after the bold face "Clover Guide".
Here is a direct link, just to be clear:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Also, your profile must be filled out with complete details as requested in the FAQ, again under "Q. Where do I start?". All seven details requested are equally important.

And if you have an issue (after following the guide), or on any other problem, you must provide a detailed description of the problem including information that helps us understand what you're doing. Always attach "Problem Reporting" files as per FAQ.
http://www.tonymacx86.com/el-capita...faq-read-first-laptop-frequent-questions.html
The required files and data are fully detailed in the last question in the FAQ:
"Q. What are typical "Problem Reporting" files?"

Thanks for the quick reply. I've been toying with some stuff since then but I'm still getting the same kernel panic. I've tried a couple different patches on AppleIntelBDWGraphicsFramebuffer (both of them are in my config.plist), barring that I've also tried changing the DVMT-preallocation via UEFI grub but I'm getting this error:

--> GUID matches expected GUID
expected a different size of the setup variable (got 1400 (0x578) bytes). Continue with care...
Successfully obtained setup variable from VSS (got 1400 (0x578) bytes).
Setting offset 0x18c to 0x03
error: can't set variable using efi (error: 0x00000000000001a).

I've updated to the latest BIOS (ABCN96WW in my case). I noticed the problem is the same as ryman's Yoga 2 in this thread, even to the point of having the same setup variable offsets, and he fixed it by downgrading the bios but Lenovo has not published the previous versions of my BIOS. Is there anything to be done or should I seek out an older version of my BIOS?

Doing this workaround seems to have been successful, but I'm not sure it has changed anything, as I still get the kernel panic...
Incidentally, Windows shows my video memory for intel 5500 as 128mb but I'm doubtful if that number actually means anything

As per guide, you must use an invalid ig-platform-id when you have 32mb DVMT-prealloc.
Read the relevant section of the guide carefully.

She boots! Thanks for leading me in the right direction. If I can get everything configured properly I'll likely make a guide for this machine
