rMBP keyboard stopped working

[UBS28]

My keyboard stopped working. A restart however fixed it.

Is this a known software bug (Mavericks 10.9.2) or could there be something wrong with my logic board?

Did you notice this in the previous updates? If it does happen again do note what exactly causes it, im sure this could be a software bug as on my retina early 2013 sometimes the trackpad and key oarx would go unresponsive a software update fixed it. But i guess it would be best if you notice it again to call apple care and check for answers or etc.
