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. -- Emmanuel Dreyfus m...@netbsd.org
