Okay, obviously something is wrong. Adding another console line isn't
fixing anything, its just allowing you to flounder on a little further.
IMHO, adding another console line isn't going to help and will only add

Sure it does. You have to enable it, then add some progress lines to
help narrow down where you're panic'ing/hanging. You can even use the
progress facility to dump the __log_buf.

I'm taking your unwillingness to use a jtag/cops debugger as indication
that you don't have such a tool!?!?
