Use SSDT-SBUS-MCHC.aml if you don't have.
@StefanAM Thanks for the suggestion. Have you seen this solve a similar problem before? I realized this happened after the latest Catalina update that hung on install, so I am rebuilding the machine to see if the problem is not with the boot loader (I have now observed it happening with both Clover and OC).
