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'"
Increase the size of CONFIG_SYS_PBSIZE so that it can store the error message and allows the error message to be printed correctly with no hang.

This problem affects many boards.
Maybe a global fix is to add a CONFIG_SYS_PBSIZE entry into config_fallbacks and remove its definition from the board config files when it is defined as: #define CONFIG_SYS_PBSIZE (CONFIG_SYS_CBSIZE + sizeof(CONFIG_SYS_PROMPT) + 16)
IMHO this is much better as fixing each single board.
or even when it is equal to CONFIG_SYS_CBSIZE.
I would not add any further check : if a board maintainer add CONFIG_SYS_PBSIZE to each own config file, he must know what he is doing. If it is not set, config_fallbacks defines CONFIG_SYS_PBSIZE
