Haven't looked at it yet, I just hit this one while riding the
train this morning and connecting to someone's adhoc station.
[43559.227490] wlan0: Selected IBSS BSSID 2a:51:0a:35:5c:a1 based on configured SSID
[43559.258660] ath5k phy0: bf=efb0b680 bf_skb=(null)

[43633.646860] =========================================================
[43633.646864] [ INFO: possible irq lock inversion dependency detected ]
[43633.646867] 2.6.31-rc6 #179
[43633.646870] ---------------------------------------------------------
[43633.646873] cc1/18756 just changed the state of lock:
[43633.646876] (&local->sta_lock){..-...}, at: [<fa244acd>] sta_info_insert+0x91/0x174 [mac80211]
[43633.646900] but this lock took another, SOFTIRQ-unsafe lock in the past:
[43633.646903] (todo_lock){+.+...}
[43633.646906]
[43633.646907] and interrupts could create inverse lock ordering between them.
[43633.646908]
[43633.646911]
[43633.646912] other info that might help us debug this:
