Found the reason,

-v11: change far jmp back to far return to initial_code, that is needed
     to fix failure that is reported by Konard on AMD system.

works well on on AMD 4 sockets that I found.

update the for-x86-boot branch, please check that.
     git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git
for-x86-boot

Thanks a lot for the testing on AMD system.

Yinghai
