Can  you give us some insight on your render settings?
Are you using interior mode? How many samples?

Hmm, thank you.

So without knowing what materials you're using, what your lights are setup as or what else is in the scene. I would recommend turning off caustics, you won't need them if you're not actually rendering anything that has transparency. (As far as I can tell, you do not). If for some reason you need them on still, I'd turn on interior mode and let this cook a little longer. If you need to speed up time, lower your ray bounces a lot (again, no transparency, so you don't need that many). You could also turn down the indirect bounces to speed things up.

Essentially, you have really HIGH settings that do not need all these extra calculations, and your probably dealing with really long render times. First turn the settings down and see what you need, then let it render longer (or turn up the sample rate in the render settings).

Hope this helps

What DMerz III said. Those don't look like default settings to me,  use one of the radio button presets to start off with, good one is the product preset. Then let'er cook for a while. Even with the white splotches should go away if you let it bake long enough. But yeah, if there is no need for caustics turn it off.
