If so, I just asked for e0ab0ff104cb0e817d47a1a2a235f915ec1a31f4 to be MFCed as that likely prevents your wlan from starting if the wlan interface is not there yet by the time we run (the "global") netif start. If this was on HEAD please let me know and I'll have to dig deeper. Later, /bz -- Bjoern A. Zeeb r15:7
