Using model - issue while using methods

looks like it's conflicting with the CI logging class, take a look at systems/codeigniter/Common.php

Code:

/**
* Error Logging Interface
*
* We use this as a simple mechanism to access the logging
* class and send messages to be logged.
*
* @access    public
* @return    void
*/
function log_message($level = 'error', $message, $php_error = FALSE)
{
    static $LOG;
    
    $config =& get_config();
    if ($config['log_threshold'] == 0)
    {
        return;
    }

    $LOG =& load_class('Log');
    $LOG->write_log($level, $message, $php_error);
}
