First, this kernel has lots of patches, including patches to the station hashing.
http://dmz2.candelatech.com/?p=linux-4.4.dev.y/.git;a=summary
But, my hashing patches cannot cause an error return as far as I can tell,
so I'm not sure this is my bug or not.
And, I'm running custom wave-2 ath10k firmware with 35 or so station
vdevs doing encryption, and with a lot of ath10k patches from newer
development kernels....
Test case was to bring up the stations. All but one (sta28) came up fine.
Seems it had issues on the initial connect for one reason or another, and then
on deauth, removing from the has failed (sta_info_hash_del).
I'm curious if anyone has seen anything similar lately?
Splat is below...narrative continues after...

Later, the station cannot be re-added because it at least partially exists in the
stack. That ath10k splat seems to be because there is no channel-req associated
with the station.

There seems to be no good way to recover from this.
There is a bunch more craziness in the logs too. I've uploaded them here in case someone
wants to take a look.
