If you have an ath(4), wpi(4) or iwi(4) wireless network link, and you’re running DragonFly-master, please update. Sepherosa Ziehau has pushed Johannes Hoffman’s wlan_serialize branch, which means bringing up wlan0 is a bit easier – and less crashy.
It needs to be tested for wpi(4) and iwi(4), however, so if you have success or failure with those devices, please say so in reply.
