Doing some Print debugging, I'm finding the first AllocatePages in
efi_md_init hangs. Which is a little interesting, since an AllocatePages
in efi_heap_init has previously succeeded? My current debug log:

efi_main starting...
efi_heap_init...
AllocatePages addr: 0000000100000000 sz: 256
heap_start: 00000000&E66F000
efi_md_init...
startprog64_size: 8480
AllocatePages addr: 0000000100000000 sz: 3

Anyone have any hints at this point? Everything looks sane to me.
