https://bugzilla.kernel.org/show_bug.cgi?id=77201 --- Comment #14 from registosites@xxxxxxxxxxx --- I have tested v3.15-7257-g963649d and applied the patch you attached and it still hangs when trying to bring the cpu online. The earliest 3.14 I could quickly test right now was 3.14.1 (provided by the distro I'm using) and it also fails when trying to bring the cpu online. If it helps, 3.13.8 worked fine (suspend and hibernate, didn't actually test cpu offline/online).
