Ugh, well that is not good.  Does ndiswrapper work?  Unless anyone
else has ideas, I would suggest capturing a trace using mmiotrace and
ndiswrapper to see what is going on.  Someone on ath5k-devel list
might have a better idea.

By 'hanging' I mean the register writes cease to do anything useful
and the card basically stops responding until you power off.  Madwifi
will even give "Card didn't behave as expected" in this case.  -EIO
means it couldn't wake up the chip after 1s, so if the first call to
ath5k_hw_set_power that doesn't work, we'll need a trace to see what
differences there are in a working setup.
