Do your packages have SRCPV in PV?

SRCREV isn't included in sstate signature without SRCPV in PV or this
patch:

commit a414b17e1d783ad68a2d0f7d5922967449c05797
Author: Ross Burton <ross.burton at intel.com>
Date:   Mon Sep 29 15:40:14 2014 +0100

    base.bbclass: add SRCREV to do_fetch() hash

but even with this patch it doesn't work for recipes with multiple
repositories (you can find an e-mail with more details in oe-core ML).
