Hi,
I noticed this warning in the log just by accident, I haven't had any
problems. I'm running latest wireless-testing (commit 9d9540984a) on
thinkpad x230 with Intel 6205.

These must be during suspend/resume, care to post a backtrace or two
(are they all identical?)

These are with various versions of wireless-testing, I update pretty
frequently.

Smells like a race to me. We probably requested aggregation and then
deauthenticated, thus killing the session data. Then the driver probably
had a bug and said it started the session or something ...
