1) 628859e8621cb is part of large patchset landed in 4.16 kernel and 4.14.151 stable release
2) 4.14.151 mainline build kernel is ok to bring up SMP CPUs (See #5, kernel oops on SMP initial)
3) 4.16 mainline build kernel is ok to bring up SMP CPUs
So, we can not report 4.14.151 and 4.16 has this issue. I am going to check anything missing between 4.14 and 4.15
