When one cpu is set to offline, the caller process will hang, according to
the trace data, the problem lies in the refcount error in cpufreq driver,
cpufreq_cpu_callback will wait for completion policy->kobj_unregister
which is nerver completed because a refcount error in function
__cpufreq_remove_
When one cpu is set to offline, the caller process will hang, according to
the trace data, the problem lies in the refcount error in cpufreq driver,
cpufreq_cpu_callback will wait for completion policy->kobj_unregister
which is nerver completed because a refcount error in function
__cpufreq_remove_
