Unfortunately, 3.18.x is painfully old, and not the latest mainline kernel.
As well, reporting to bugzilla is legacy (as well as premature), as it is not the preferred method to report bugs to upstream, and the latest mainline kernel has not been tested yet (as requested by upstream).
Alberto Salvia Novella, thanks for your help.
