Hi, Konrad

Borislav has reported the BUG before, and we already figure out the
issue was caused by gov_queue_work() passed an offline cpu to
mod_delayed_work_on(), you could get the conversation here:

	https://lkml.org/lkml/2013/5/20/297

I've cc the related folks, and I still suggest we could try:

diff --git a/drivers/cpufreq/cpufreq_governor.c

 }
 EXPORT_SYMBOL_GPL(gov_queue_work);

firstly, would you like to apply it and see whether the problem get solved?
