I've compiled the sources and struggled with my config file (if anyone has info on setting up kismet.conf for an airport 802.11b w/ viha drivers I'd gladly listen.) Anyway, every time I run ./kismet as su'd root my powerbook has a kernel panic. This has only happened after I have commented out the part of the config file that deals with 802.11a channels. Perhaps I should comment out the 802.11g part...?
