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.
