/netbsd:
I don't know if it is feasible but it would have been nice just to get an error in this case instead a full blown panic. I believe one of the usb drives was bad which caused the failure
>How-To-Repeat:
I think this may be very difficult to reproduce, but newfs two usb drives at same time when one is bad.
