no. tgl is from the dtk it doesnt matter os x version. sometimes i get a boot hang if not removing the usb pen after boot starts

 

or if you mess with /S/L/E maybe it bugged /L/E

 

can you load the kext with kextload ?

 

gonna remove the tgl graph from nblue just a sec

k download again info.plist as frame only ids

 

if you installed this to /S/L/E it will cause a bug

gonna remove this ids from sle_internal zip just in case

done srcs are on this page

 

hmm idk it hangs at gtrace point 1. it's very strange

maybe cause your display uses applebacklight?

my displays is not using it

Apple Backlight is usually added via the nblue plist, but it wasnt modified when i was testing.

open log console and redo kextload so you can check the error. seems like permissions or dependencie error. use tgl as console filter

anyway u found the cause

 

hope this is not some extra dependency caused by sonoma

com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer exists in Optional(file:///Library/Extensions/AppleIntelTGLGraphicsFramebuffer.kext/), telling kernel to mark as available
KextLog: AuxKC bundle com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer marked as loadable
loading extension from in-kernel fileset: com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer (will start, will match)
OSMetaClass: Kext com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer class AppleIntelPlane is a duplicate;kext com.apple.driver.AppleIntelICLLPGraphicsFramebuffer already has a class by that name.
Kernel Extension ALLOWED: Kext ((null), com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer) version: 4eb03d42eb57e89ec6ed82f4e519e5685e636614
Kext com.xxxxx.driver.AppleIntelTGLGraphicsFramebuffer did not start (return code 0xdc00400a).

same id in com.apple.driver.AppleIntelICLLPGraphicsFramebuffer ? 0x9a49 shoudn't match system icl

 

i've got that error some time ago also. cache error from old kexts maybe

 

that is cause u booted wit icl kext

 

that's why u got that error

 

boot without nblue to test

 

glad i remenbered that

 

anyway just reset /L/E cache after boot.

 

i think the cache might be ok so hang issue is something else. test nblue binary with card id on icl sys frame to check (leave tgl card id empty)

no wg no nblue boot with zero graph kexts.

 

idk if what asus sayd about lilu kext loader loop is causing some type of hang

 

tying to understand this code. maybe relates to CsbProcModeSelect parameter from info.plist

scheduler 5 doesnt load firmware. trying to guess how this works and why it is failing
