CPU:
ryzen 3 3250U
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?
