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
IssueBoot 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/_PS0methods on this laptop?Thank you — will provide logs/debug photos if needed!
