In case of carl9170, these messages indicate that some non-802.11 transmitter
is near by (and confusing the chip a bit). These messages (and the associated
issues) can magically appear and disappear... So, chances are that they reappear
sometime later. There's little the firmware can do here.

Oh, I tried that back in October 2013.

But no agreement has been reached. And 1.9.6 is good enough to download
the later firmware releases though. I'm sorry, but that's how it is at the moment.
But if you want to help, you could make a patch (the way Rick/Ben wants it) and
post it here (linux-wireless@vger.kernel.org). I can't do it, I tried and failed several
times. If you are interested: The firmware is under GPLv2, no sign-offs or acks
(from QCA, me or anyone else) is needed, you (or anyone else interested) can
go right ahead.
