Yes, i'm doing the tests using the dongle connected to a tplink mr3220
running openwrt trunk for ar71xx.
The mr3220 has a usb port where i connect a tplink wn722n usb dongle.
The internal wifi of the router uses ath9k driver and works just fine.
The dongle uses ath9k_htc and presents the problem described, from the
moment openwrt devs upgraded trunk to use compat-wireless 2012-04-13

thanks for the patch, i found it strange because it seems related to
IBSS, but i just tried it anyway
unfortunately it didn't solve the problem :(

Please note the bug I described happens when in client (managed) mode,
and it is in fact a regression because it was working fine on 2012-02-27

something along the development up to 2012-04-13 caused the bug

You had mentioned earlier that you were recompiling OpenWRT for bisecting,
are you using an AP running OpenWRT ? On what platform is the dongle being
used ?
