We saw in our case a possible data corruption in the tty layer : in n_tty the n_tty_receive_buf can drop characters if it can't copy all of them in the tty circular buffer.
A fix should be to remove tty->receive_room and make n_tty_receive_buf return the number of bytes copied.
A patch to correct this was done in b1c43f82c5aa265442f82dba31ce985ebb7aa71c, but it was reverted because it was buggy.
May be you should check that this is not your problem.
