Gigabyte H87M-D3H/i5-4440 doesn't boot completely (without -igfxvesa)

Hi,

I've installed High Sierra successfully using OpenCore. However, when I try to boot into the system, it briefly displays the Apple Logo + Progress Bar (after a ton of verbose logging), before it crashes (the logo disappears and i'm left with a black screen - no logs at this point). It stays stuck at this point, until I force restart.

The i5-4440 has Intel HD4600 which should be natively supported (and, I don't have a discrete GPU). I've tried every desktop platform-id for Haswell from this list. System boots completely when I use either of these flags (-x or -igfxvesa). Since, it boots with -igfxvesa (which disables graphics acceleration), I believe this to be some form of graphics issue.

Intel Processor Graphics Memory Allocation = 64M (this should be DVMT Prealloc set correctly in my BIOS).

VT-D is disabled. Also, tried with boot param dart=0.

With -igfxvesa set, my WhateverGreen logs from the verbose booting are

Unfortunately, the logs from normal boots (without -igfxvesa) don't seem to be written to disk. 'sudo log show | grep -i whatevergreen' doesn't have any lines related to that boot. However, on display I do see it says hdmi patching framebufferid 0x0d220003 succesful.

I've tried iMac14,1, iMac14,2, and iMac15,1 in my SMBIOS with relevant serials generated by macserial.

My OpenCore config.plist can be found here. I'm using WhateverGreen v1.3.5 and Lilu 1.4.0.

Would appreciate some ideas on how to proceed from here. Thanks
