E5470: Issues with BrcmBluetoothInjector and slow boot on macOS Monterey beta1

[PMD]

My laptop failed to boot while updating to macOS Monterey version. I don't know why when I disabled BrcmBluetoothInjector in config.plist it can boot normally. How can i use bluetooth without this problem?

 

 

I'm using Latitude E5470 with HD 530 and my wifi card is DW1820A.

Bluetooth is a little buggy for the moment in Monterey 1st beta. You'll probably have to wait. Also keep in mind that, if you've kept the same versions of Lilu + PlugIns as ou used in Big Sur, you probably need the beta boot arg for all. As stated at IM, PMHeart has now updated Lilu & PlugIns for Monterey so I would advise you to update and renew your tests. Just check the usual Dortania repo:

@Hervé Is there a way to use this Bluetooth dongle temporarily until that problem is solved? If I remember correctly, this dongle is fully compatible with Catalina

 

[Hervé]

I've no idea, try out by yourself.

@Hervé Do you have this problem on Monterey? Besides, mine has very long boot time.

clear nvram.

[Hervé]

@PMD no such issue at all; in fact no issue whatsoever. Using Fenvi BCM94360NG which is fully supported OOB.

@Bronxteck I tried resetting NVRAM at OC picker but the issue is still there

 

@Hervé Can you check my config.plist above if there's an option that makes my laptop take a long time to boot?

[Hervé]

My findings below.

 

ACPI patch:

• you rename ECDV to EC when you actually inject the SSDT-EC-USBX table; renaming is therefore unnecessary and should be disabled/removed.
• you inject SSDT-HPET table yet not applying any renaming for HPET or its _CSR method. You would most likely need that for SSDT-HPET to have any effect.

Device Properties:

• you inject SKL framebuffer layout 0x191b0000 for HD530. I would have expected 0x19160000. Are you getting graphics acceleration ?

NVRAM:

• you'll probably have to add -lulibetaall and -wegbeta boot args to avoid system reset at boot time and KP after wake.

@Hervé I removed ECDV to EC patch but it can’t boot now. And how can I do with HPET?

About framebuffer layout, I see 0x191B0000 match HD 530 in Hackintool

I updated kext to the version in https://github.com/dortania/build-repo/releases. Do I need to add those boot-args
