This is in 3.7.5, plus one ath9k patch to over-ride eeprom regdomain.
Code that causes this is here...I seem to have a good test case for
this currently, so if there is any other debugging I could put here
that would be useful, let me know.
if (WARN_ON(!tid_tx)) {
ht_dbg(sdata, "addBA was not requested!\n");
goto unlock;
}

Heh, I think Kalle just had the same. Do you have the ht_dbg()
statements (i.e. HT debugging) enabled?

Please. Actually, if you can (and it applies) this patch would be
helpful too:

I added that, and the patch that allows two VAPs to register for
beacons so I can run both VAPs I have configured on this system...
I can grab more history if it helps...
