What is fips mode? How to enable it?
FWIW, this likely results from some failed clean-up after ieee80211_register_hw fails...
renamed, because i noticed this on iwlagn with john's test kernel
FWIW, I think this actually is ath9k-specific. The similar behavior on iwlagn was actually caused by the 1st fix attempt in bug 608704. After fixing that issue, I was still able to get this ath9k failure. I'll attach a pic of the failure on my local machine.

Note that this is without the fix to allow FIPS mode to work (but with the fix that allows rmmod of iwlagn) -- with that in place I suspect this won't happen at all.

verified with adapters, where i detected. rmmod iwlagn and ath9k works as expected
Patch(es) available on kernel-2.6.32-52.el6
Could you please retest so we can close this? Or you can alternatively write here hostname where we can retest.
tested on frankenstein-wifi-01.rhts.eng.bos.redhat.com, it has several types of wireless devices. Tested with all of them under fips enabled system.
