Inspecting EFI memory map, I now understand why: the kernel
is too big to fit in the coventional memory mapping where
bootstrap code attempts to copy it.

kernel size: 0x1b34820
memory mapping size 0xf00000

It seems we do not check for room, we just load at ELF 
header load address with the hope everything will be okay.
