Im not really sure about debugging; I can not tell about early kernel, =
but I=E2=80=99d check if the kernel/module locations conflict with efi =
memory map items=E2=80=A6=20

The same issue can be seen with vmware fusion, it is not 100% repeatable =
but I=E2=80=99d say, 95%, starting grab_faults, perhaps ls or some other =
random command, and boot -v may actually start the system up.=20
