Please, apply that two patches. First one: http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=3311abbbbff1719bbbc8208761e4a75f095f383c Second one is the one I attached. You can revert your switching to PIO and debugging messages if you wish. That doesn't matter. My idea of what is happening: 1) We try to use newer firmware which does not forgive us broken TX header anymore 2) Radio does not transmit, or transmits rubbishes 3) mac80211 detects failure of transmitting and hits some allocation loop, memory leak If that patches help, it means we satisfied newer firmware and TX transmission goes fine. However there still probably is some alloc bug in mac80211 that was exposed by b43. -- Rafał
