Download denzil SDK for arm which is gcc 4.6 based and compile kernel
using that and see if that boots. There could be some kernel+toolchain
interaction w.r.t gcc 4.7 which is what is
default in current master/(would be 1.3) release, sometimes gcc
exposes latent bugs in kernel
and at times its wise versa
