The setup you are using there is not clean and has never been
supported - you load a (heavily) modularized kernel 3.19 but
provide it with an installer initrd containing only modules for
kernel 3.16, so it might well be that the kernel tries to load
some required modules but fails to do so because of the version
mismatch.
Try to install a system as intended with kernel 3.16 and the
matching initrd - which does work for you as stated above - and
then install the kernel 3.19 package from experimental into
the final system.
