Open Core > Panic after sleep. How to read panic reports?

[coolqf]

How do I interpret the attached report? After sleep, my computer always panics and I have to manually power it down and then power it back up.

I'm only using an iGPU and have my monitor connected to the computer via an HDMI cable.

I used clean installed with OpenCore 0.5.5. My computer hardware is listed in my signature.

This panic is IGPU related. Check your IGPU configuration in config.plist.

Thanks for your response. Can you guide me to a link on how to do that? I used the OpenCore Vanilla installation guide, and have depleted all possible things that I missed. I just need a different source to help me troubleshoot this.

Here's the link i've been using as a guide:

Any guidance? I guessed it was iGPU related. Thanks. Anything to do with the kexts or just the config.plist? I'm absolutely stumped as to how to proceed. I've attached my config.plist.

I'm not sure if it will help, but you can try deleting the following...


Also, make sure you have the appropriate SSDT-AWAC.aml, SSDT-PLUG.aml, and SSDT-EC-USBX.aml can only help.
