aaaa is 0101010101010101. That's too coincidental for me to be comfortable. Is that the pattern that uninitialized memory has?

I'm seeing this with
make bin-x86_64-efi/snponly.efi DEBUG=netdevice,nii EMBED=testscript.ipxe

Are you printing out the reg, and can you run this on a working machine as well? (and do we know if snponly.efi works with working firmware?)

If you can join us on IRC maybe you and Michael could figure this one out?
