Question

Is there any FOSS Stack Exchange clone (like askbot OR osqa) with Git backend or more generally which allows me to do the following (for organizing personal knowledge in Q&A-format):

Have a copy locally on laptop A and B (which should work independently offline)
Sync/merge (easily) laptop A's and B's copies periodically when A and B have network access, with proper handling of conflicts etc.

Note that the main point in this question is to have good sync capabilities. For wiki software I know some solutions like ikiwiki. But is there also something for Q&A-software?

Explanation / Answer

Yes you can get a Stack Exchange clone. Try Discourse. It is built by the same people who built Stack Exchange. It has all the features you are looking for except for the sync/merge option which I think you would have to do by a different way. Some of the features of discourse are:

Free-open source :
Topics and tags
Voting system
Mobile support
Attachments
Users with different kinds of permissions

There is a piece of software called Navicat though which makes syncing two databases which have similar or same schema easier. The software can find the diff between two schemas and will suggest insert update queries based on the diff. But the final change (sync) will have to be done by manual supervision.
