Hmm, given that Mikulas in
https://lkml.org/lkml/2014/2/26/537
offered a diff of linux-3.13.5 files, it truly seems (shock! ack! noo!)
that that indeed may have been a regression at <= 3.13 proper even
(which may pose interesting questions about the level of testing coverage
we still enjoy [not!?] in this hardware area).

Oh well, seems I'll have to prepare/build 3.13 now...

Thanks,
