I think this is only addressing the symptoms - what we should be doing instead is asking ourselves why are we even scheduling work on a cpu if the machine goes offline?
I don't know though who should be responsible for killing all that work - the workqueue itself or the guy who created it, i.e. cpufreq governor...
