cfg80211 isn't loading, so mac80211 can't find it's symbols, and ath5k can't find mac80211's symbols.

config WIRELESS_OLD_REGULATORY bool "Old wireless static regulatory definitions" default n ---help--- This option enables the old static regulatory information and uses it within the new framework. This is available temporarily as an option to help prevent immediate issues due to the switch to the new regulatory framework which does require a new userspace application which has the database of regulatory information (CRDA) and another for setting regulatory domains (iw).
For more information see:
http://wireless.kernel.org/en/developers/Regulatory/CRDA http://wireless.kernel.org/en/users/Documentation/iw
It is important to note though that if you *do* have CRDA present and if this option is enabled CRDA *will* be called to update the regulatory domain (for US and JP only). Support for letting the user set the regulatory domain through iw is also supported. This option mainly exists to leave around for a kernel release some old static regulatory domains that were defined and to keep around the old ieee80211_regdom module parameter. This is being phased out and you should stop using them ASAP.
Say N unless you cannot install a new userspace application or have one currently depending on the ieee80211_regdom module parameter and cannot port it to use the new userspace interfaces.
This is scheduled for removal for 2.6.29.
Is this not clear enough?
