Solved After upgrading my bios rom, my hackintosh suddenly failed to start

You are using an SSDT-EC.aml that is configured for an Intel system. You need to use one that is configured for an AMD system. Preferably one with the USB power settings included in the combo SSDT, like the one attached below.

Posting a partial image of the verbose text from your failed system boot is a complete waste of time. The part you have posted can easily be taken out of context, especially by someone who knows little about hacking a standard AMD system.

As you updated your bios, have you edited the new bios to work with macOS?
