[Lenovo Legion 5 15ACH6] RT-GV wake-failure — Ryzen 5 5600H / Vega 7 — Ventura / Sonoma

[samael_me]

System Specs

• Model: Lenovo Legion 5 15ACH6
• CPU: AMD Ryzen 5 5600H
• iGPU: AMD Radeon Vega 7 (Cezanne / Renoir) — via NootedRed
• dGPU: NVIDIA RTX 3050 Ti — disabled via -wegnoegpu
• Ethernet: Realtek RTL8111
• WiFi: Realtek 8822CE
• Audio: ALC287
• Target OS: macOS Ventura 13.x / Sonoma 14.x

### Issue
Boot hangs at: <rt-gv> wake-failure

Screen freezes → fans ramp up → system eventually shuts down.
### What I've Already Done

• BIOS Settings:
• Secure Boot → Disabled
• XHC1 → Disabled (per known Legion 5 fix)
• PTT → Disabled
• ASPM → Disabled
• GPU Mode → Hybrid
• Boot Mode → UEFI Only
• Kernel Quirks:
• IncreasePciBarSize = True
• - Boot Args: ( -v keepsyms=1 npci=0x2000 slide=0 -vi2c-force-polling -wegnoegpu debug=0x100 )
• - Kexts loaded:
• - Lilu.kext
• - VirtualSMC.kext
• - NootedRed.kext v0.8.10 / v1.0.0 — tried both
• - AppleALC.kext
• - NVMeFix.kext
• - AirportItlwm.kext
• - VoodooI2C + VoodooI2CHID series
• - BrightnessKeys.kext
• - BlueToolFixup.kext
• - RestrictEvents.kext
• 
  
• - EFI Base: ducviet5138 / kalkmann / Lunarixus Legion 5-15ACH6 builds- Attempted Fixes:- Disabled NootedRed during install → still hangs
• Added gfxinitwait=1 → no change
• - Multiple boot arg variations
• - Reset NVRAM repeatedly
• - Swapped USB ports / recreated installer
• ### What I Know
• - My Vega 7 is Cezanne — supported only via NootedRed- Other Legion 5 15ACH6 + 5600H owners have this working- Discord reports suggest disabling NootedRed during install then re-enabling post-install — but I still hit wake-failure even with it disabled- The error points to iGPU power/initialization timing
• ### What I Need Help With- Is there an additional ACPI patch or device-property specifically for Vega 7 on this exact motherboard?- Is there a different boot-arg or framebuffer fix I'm missing?- Could this be a specific BIOS version incompatibility?- Any known workaround or patched DSDT for _DSM / _PS0 methods on this laptop?Thank you — will provide logs/debug photos if needed!

Is there an additional ACPI patch or device-property specifically for Vega 7 on this exact motherboard?

No there isn’t a patch or device property for the VEGA 7 AMD IGPU.

Is there a different boot-arg or framebuffer fix I'm missing?

No, as there are no boot arguments specifically for your AMD IGPU, other than those provided by NootedRed and/or WhateverGreen.

I use ‘ igfxonln=1’ boot argument with my AMD IGPU’s, which ensures the display is forced to be online in macOS. Yes this is a boot argument from WhateverGreen, but the Dev for NootedRed has incorporated some of the features from WhateverGreen in the AMD IGPU kext.

No idea if there is a patched DSDT for your laptop.
