query for idea about a kexec regression

While I testing efi runtime patches for kexec kernel, there's
2 machines kexec fails on them. It can be reproduced with
non-efi kernel, so it's not related to the patchset.
Problem is kexec kernel will immediatly reboot after below
smpboot: Booting Node 0, Processors # 1
The latter CPUs were not printed.
nr_cpus=1 works, so there might be some bug on smp code.
Any idea or suspection acout some patches? This is not 100%
reproducible, to me it's about 30% thus it's hard to bisect.
