FYI,

This patch, in modified form went into wireless-testing and linux-next a
few days ago

http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=3a37495268ab45507b4cab9d4cb18c5496ab7a10

And it indeed fixed a lot of our issues :). Unfortunately we still
experience failures with ath9k in AP mode with these symptoms.

We lose connectivity on STA side, we still seems to be associated but
are unable to transfer any data. Any reconnection fails.

A strange observation is that in some/all(?) cases we are able to
associate using a STA in pure A/G-mode and transfer data. 

If anyone is interested we would gladly provide dumps/debug information
on this. (Gathering dumps as we speak)
