From: Fabio Estevam fabio.estevam@freescale.com
Entering the maximum number of characters defined by CONFIG_SYS_CBSIZE into the console and hitting enter afterwards, causes a hang in the system because CONFIG_SYS_PBSIZE is not capable of storing the characters of the error message: "Unknown command '' - try 'help'".
Provide a default size for CONFIG_SYS_PBSIZE so that it can store the error message and allows the error message to be printed correctly with no hang.
