Ryzen 3 3250U (Dali) laptop: Monterey boots, Ventura/Sonoma/Tahoe freeze at "kdp_core zlib memory 0x7000"

[Zen]

Hardware: Dell Inspiron 15 3525, Ryzen 3 3250U (2C/4T, Dali), Vega 3 iGPU, 8 GB RAM, KIOXIA KBG50ZNS NVMe, BIOS 1.36.0 (InsydeH2O, no CSM, Above 4G already on, SATA = AHCI, Secure Boot off).

Working: Monterey 12.7.6 runs with OpenCore REL-109 and AMD_Vanilla patches (core count 02, Shaneee PAT patches, DummyPowerManagement, NootedRed, ForgedInvariant, RestrictEvents).

Problem: Ventura 13.7.x (Darwin 22.6.0), Sonoma 14.6 (23.6.0) and Tahoe all stop dead at kdp_core zlib memory 0x7000, with no panic and no further output.
Verified: OpenCore log shows MAT support is 1, all AMD kernel patches applied successfully, kexts injected.

Tried without change: every Booter quirk set, with and without custom ACPI/SSDTs and HPET patches, minimal kexts (Lilu, VirtualSMC, WhateverGreen only), algrey vs Shaneee PAT patches, cpus=1, npci=0x2000, the IOPCIIsHotplugPort patch enabled, SecureBootModel Default/Disabled, and an OpCore Simplify-generated EFI.
Has anyone gotten Ventura or newer to boot on a Dali/Picasso (Ryzen 3 3250U/3200U, Athlon) dual-core laptop? Any patch or quirk I'm missing?

Here is my EFI.

Where?
Again nothing attached to the post above.

How are you trying to attach the EFI folder?​

You need to Zip/compress the folder and attach the zipped container for it to work.​

Questions:
1. How have you configured your AMD IGPU?

How much VRAM have you allocated to the IGPU, it needs to a minimum of 1G to work without any issues in macOS.​

2G would be better, and is the base limit I use on any of my Hacks. But as you only have 8G RAM you will probably need the 7G RAM to run macOS.​

2. Have you used Smokeless UMAF to edit the VRAM (UMA buffer size) allocation?

I have used it without issue on a couple of Lenovo AMD laptop and a couple of HP Mini Desktop hacks.​

Hi Edhawk, thanks for the reply, and sorry about the attachments. They kept disappearing when I clicked Post, so I'm posting a link to the files instead: https://drive.google.com/file/d/1ouXM4gCPXMfDcPBWI_8uLYujzMZSItn8/view?usp=drive_link. It has my config.plist, the ACPI folder and a list of the kexts and versions. I removed the serial, MLB, UUID and ROM first.

To answer your questions:

1. I haven't changed the iGPU memory allocation. This is a Dell Inspiron 15 3525 with an InsydeH2O BIOS (version 1.36.0). The Advanced tab only shows things like Integrated NIC, USB Emulation, SATA Operation and battery options. There is no UMA Frame Buffer option, so I don't know what the iGPU is currently set to. Windows GPU-Z reports Above 4G Decode as enabled and CSM as disabled, and the BAR sizes are 256 MB and 2 MB.

2. I haven't used Smokeless UMAF yet. I'm a bit cautious about changing hidden BIOS settings on a laptop with only 8 GB of RAM. If you think it's worth trying, I'd set only iGPU Configuration to UMA_SPECIFIED and UMA Frame Buffer Size to 2G, and I'd photograph the original values first.

One thing I wanted to ask. The freeze happens very early, at kdp_core zlib memory 0x7000, before any graphics kext loads. I get the same freeze with NootedRed removed from the EFI (only Lilu, VirtualSMC and WhateverGreen loaded). Do you think the UMA size could really affect this stage?

For reference, Monterey 12.7.6 boots and runs fine with this EFI. Ventura 13.7.x (kernel 22.6.0), Sonoma 14.6 (23.6.0) and a Tahoe EFI from OpCore Simplify all stop at the same line. I've also tried npci=0x2000, the IOPCIIsHotplugPort patch enabled, Shaneee versus algrey PAT patches, and different Booter quirk sets. My OpenCore log shows MAT support is 1 and all kernel patches applying successfully.

Thanks again for your help.
