After upgrading my laptop from 8.4-STABLE to 9-STABLE, I have been
unable to use the wireless NIC. The indicator light will flash for a
moment and surrender. The error is always the same and reproducible
with "ifconfig iwn0 up". The system is 9-STABLE (r253048). This
appears to be the same or similar to PR 175053:

Any ideas on what is broken and how to get it to work?
Please Cc me as I am not on this specific list.
