I havn't verified this yet but it may have to do with dirty caches that are not written back to memory in suspend-to-ram and are thus lost. The resume code-path looks otherwise sane to me. The only thing I can imagine is that a bit in the cpu_hardware_enabled cpumask is wrong after resume. Btw. it is guaranteed that with cpu-hotplug the cpu isn't already executing processes when the CPU_ONLINE event call chain is called? At least the CPU is marked online and active at that point in time.
