this is vmlinuz, not vmlinux. This is the compressed image.

You need this:

[glauber@...aightjacket linux-glommer]$ file vmlinux
vmlinux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically
linked, BuildID[sha1]=0xba936ee6b6096f9bc4c663f2a2ee0c2d2481c408, not
stripped

instead of bzImage.
