There is no crash file generated. Could you please do a "sysctl -w ddb.onpanic=1" first, and then trigger the problem? It shouldn't leave the stack trace there and not reboot then. If you don't feel like typing it all in you could use a camera phone to take a picture of the backtrace or something like that. If you don't have somewhere to upload the image you could e-mail it to me directly. Andrew > I haven?t changed any crash parameters from the stock setup.
