    In looking at a diff in the last few days, a huge number of changes have been
    made kern/tty_cons.c by jlemon.  Since the area of the panic is around the same
    block of code there's a good chance that these changes are the cause, though I
    have not tested this.  If so, Jonathan can locate the bug much more quickly then
    I can.
