I test on my xilinx z7020 board, system reboot after rtems_bsdnet_initialize_network() returns success and a 
message "RTEMS bsdnet_initialize_network returned OK" print out.
I tried to add another printf("...") after it, no more message print out.

The previous RSB version is OK, except mixed messages.

I tend to agree, I just need to check and make sure this is the reason.
