Open-Mesh » batman-adv

When deleting the wifi interface currently used by batman-adv with i.e. 'iw dev wlan0-1 del' on an Alix board with an ath9k based wifi card with a recent OpenWRT version from the Attitude Adjustment branch (rev. 34092, Linux 3.3.8) plus vanilla batman-adv 2012.4.0 as well as some extra kernel debugging options, I'm getting the following recursive locking warning:
