--- Comment #15 from Zhenlei Huang <zlei@FreeBSD.org> ---
(In reply to Patrick M. Hausen from comment #14)
The panic error 1 indicates accessing invalid kernel address.
> sys/vm/vm_param.h:#define	KERN_INVALID_ADDRESS	1

I'm not sure how that happens. Can you please try the following:

 1. Unplug USB ethernet
 2. Boot the board
 3. On boot (when have a login prompt) plug in the USB ethernet

The screen shot helps some but it will helps a lot if you can share the
backtrace or core dump (compile kernel with DEBUG options and install gdb
package).
