Here's logs from a station system that had a problem of this nature.  Since
it should not be doing any beaconing, I guess the root cause of at least this
particular problem is different.  This is with our firmware and hacked ath10k
driver, so of course it is possible it is not an upstream problem.

Kernel is 3.14, with most of the ath10k patches from 3.15 backported to it,
plus additional patches.
