Bug: do_reset issued via netconsole does not reset mpc83xx cpu.
The do_reset routine in the cpu/mpc83xx/cpu.c file does not reset the mpc83xx cpu when issued via netconsole. Moving the console output "resetting the board." to the beginning of the routine before disabling interrupts solved the problem.
