Thanks, this appears to confirm that commit ca45de77 is the culprit:
ogasawara@tyler:~/linux$ git bisect good
ca45de77ad706e86b135b8564e21aa2c8a63f09b is the first bad commit

mac80211: tear down BA sessions properly on suspend
Currently, the code to tear down BA sessions will
execute after queues are stopped, but attempt to
send frames, so those frames will just get queued,
which isn't intended. Move this code to before to
tear down the sessions properly.
Additionally, after stopping queues, flush the TX
queues in the driver driver to make sure all the
frames went out.

I've subsequently built an Ubuntu test kernel with the above commit
ca45de77 reverted. It's basically the 3.0.0-8.10 Ubuntu kernel minus
commit ca45de77. I've placed it at the usual location. Version string
is 3.0.0-8.10+lp811214v2. Please test and let me know your results:
http://people.canonical.com/~ogasawara/lp811214/
If that test kernel works, I'm also going to have you test the latest
v3.1-rc1 mainline kernel which just came out to confirm there hasn't
been a subsequent patch applied which resolves this regression. I may
have to build the v3.1-rc1 kernel for you as it appears it's not yet
available at http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.1-rc1-oneiric/ . Thanks!
