Viresh,
Got that box and did some debug, found the policy->kobj is not initialized.
So the race happened between cpufreq_cpu_get() and
__cpufreq_add_dev(), and verified 'this' race could be fixed by commit
6d4e81e cpufreq: Ref the policy object sooner
I have reboot the box with crond for more than 12 hours, no warning found.Oh, great. Thanks for your work Ethan. You want this to be pushed for 3.18 stable kernel, right? I will see what I can do.
