[-- Attachment #1 --] FWIW I just started experiencing a panic that seems to happen in the igmp code whenever I attempt to "dhclient wlan0"... I'll try to get more info for ya tomorrow. The short story is that I just reverted a patch I had made to remove USB-NDIS stuff (because my adapter is PCI), since I saw that the ndis_usb --> ndis_usb2 fix was committed. I can safely use my system on the wired network (bge0) though, and wpa_supplicant seems to work alright on the ndis card.
