Can you try the different 3.12-rc kernels? The information that this was
introduced in 3.12-rc1 as opposed to a specific -rc>1 releases may help
the guys here to pinpoint what exactly caused the behavior change on the
receiver side.

v3.12-rc1 to -rc7 is available as prebuild package on the ubuntu mainline kernel
archive [1] aswell.
