Kernel Panic on Shutdown in High Sierra

[8Cores8Threads]

If it's giving you that error, the IGPU should be enabled. Do you have 64MB or more assigned to IGPU in BIOS?

Are you on High Sierra or Mojave?

I have attached my BIOS settings. I am running High Sierra.

If you disable IGPU, does the system run reliably? Do you still get panics?

Nope. Same thing. I don't know if this panic log is different.

I don't get it...

Still Intel graphics problem and IntelGraphicsFixup is still loading.

I don't know how to exorcize IntelGraphicsFixup.

Is there any other place where IntelGraphicsFixup could POSSIBLY be hiding?

/EFI/CLOVER/kexts/*
/Library/Extensions
/System//Library/Extensions

And cached :
In Terminal :

sudo kextcache -i /

Or try booting with -f UseKernelCache=No.

I tried all of the above. There were intel graphics kext files at System/Library/Extensions but no IntelGraphicsFixup. The commands & boot arguments didn’t work either. Same issue on reboot.

You can use an app such as FindAnyFile to locate the kext.
You can look in System Information - Software - Extensions also.

FindAnyFile didn't find it on the hard drive. And System Information - Software - Extensions didn't have it either. This is so weird.
