Unity 5 stuck on 7/11 Light Transport

I recently shifted to Unity 5.1.1 f1. I know someone will say turn your whole scene non static, but i cant. I can’t even turn my scene environment to static. Because it keeps on baking and stuck there (7/11 Light Transport | 1 job)

It does not happen for small scenes (very small with few objects ) but when i design a city or something even close to big. It takes too much time converting to static because of this time consumption.

I have to create Enemy AI which used baked environment, but it wont let me do that as build does not get.

Plz help me out

I dont think this is a problem with the navmesh baking instead its probably something to do with light baking.
