This has been running in my mind since few days... That we have fixed cpufreq core and all other drivers for transition serialization but what about powernow-k8? It is somewhat special (even more than exynos5440).. It queues a work from ->target() and may or maynot send notifications at all..
Finally I have got a solution now (detailed logs in the patch).. These must go with following patchset:

Compile tested only..
