Also make sure you do have updated firmware.

r355347 by itself does not really look like it should cause infinite loop on normal input, but there we would need to check what we do get from keypress and then we will see.

Unfortunately I do not have hw to check, so we would need to use your help to check what is really happening there.
Please poke me directly if you need help about constructing the printf() statements to extract the information.
