I used to run into this also.  Please check, and reply to list, if you are
using a tag in any of the recipes, and if changing to SRCREV=<hash> in all
recipes solves the problem.  

Here is a reference to an earlier discussion - I think it is commonly 
recurring question.  (Maybe you can propose a change to the docs, to
indicate this near the description of the BB_NO_NETWORK variable?)

Hope this helps,
