It's a problem with USB Audio. I think it has to do with streaming DATA to both busses at the same time. (In the case of iTunes, one application is sending audio files to the iPod, and audio DATA thru the USB Audio) When listening to ANY audio, and copying files to my iPod, the audio would lock up (in all applications). When this happens, unplug your speakers, plug them back in, and watch the kernel panic. (unless they fixed it. I haven't had this problem since 10.2, but I also avoid listening to audio while copying files over firewire.) jesse .
