In my kernel logs I see the following:

I did a search for this issue and only found other bugs indicating that this should be reported upstream:

A mailing list message:

And a possible duplicate:

My /proc/version:

Linux version 4.0.0-wl-ath+ (root@catelyn) (gcc version 4.8.4 (Gentoo
4.8.4 p1.5, pie-0.6.1) ) #14 SMP Thu May 7 18:26:16 AEST 2015

I am running the ath+ branch because my Wi-Fi will not work on the current kernel (attempted linux-4.0.4-gentoo and Wi-Fi failed to load firmware, bluetooth had exact same message in kernel logs as reported above). I'm running commit 4b9abafd of the kvalo/ath fork with the atk10k firmware files from my own sumdog/ath10k-firmware fork.

Is there an official bug in for this issue yet that I can watch? Are there any dfu files I can try out there for my specific device? I can build any kernels you need if you want more specific debugging information.
