Im not really sure about debugging; I can not tell about early kernel, but I’d check if the kernel/module locations conflict with efi memory map items… 

The same issue can be seen with vmware fusion, it is not 100% repeatable but I’d say, 95%, starting grab_faults, perhaps ls or some other random command, and boot -v may actually start the system up.
