You should not need to be specifying the revision within SRC_URI as you are 
doing, however, it is correct that you must specify the revision in SRCREV and 
that revision must be the full SHA1 hash and not just a tag or branch name. 
The reason for this is that tags are not fixed and could change, therefore if 
one is used we must query the server and resolve it to the current SHA1 hash 
every time the recipe is parsed.

Cheers,
Paul
