3.4-rc smpboot: do_boot_cpu failed(-1) to wakeup CPU#1

[shrybman]

All 3.4-rc kernels I have tried displayed this issue.


This report looks similarÂhttps://lkml.org/lkml/2015/9/26/165.
I also have a Core 2 cpu on a Asus P5B (not deluxe) board.

I took a guess and got lucky.


RevertingÂ"x86/smpboot: Remove APIC.wait_for_init_deassert and atomic init_deasserted" resolved the issue.
