This is a kyocera device that looks like a serial adapter behind an ohci usb controller, and uses the airprime driver (for usb device 0c88:17da). The actual IP networking is ppp over that serial adapter. The connection is slightly flaky (I blame this on the Verizon coverage), so I end up restarting things every so often. The point of this email (at last) is that I've just seen my second panic (only info: blinking caps lock led, since I've been in X) that seems correlated to stopping/restarting pppd. Sorry for the lack of detail -- I've just switched to running in the console so if I can provoke the crash again I'll get a little more info. I just wanted to mention this in case someone has seen something similar or has any good ideas about how to capture debugging output on a laptop (when I'm not home and have no other boxes handy). - R.
