Can you please add this line:

   printk("PPS-TEST port line %d\n", port->line);

into file drivers/serial/serial_core.c as follow:

   int uart_add_one_port(struct uart_driver *drv, struct uart_port *port)
   {
           struct uart_state *state;
           int ret = 0;

           BUG_ON(in_interrupt());

           if (port->line >= drv->nr)
                   return -EINVAL;
   printk("PPS-TEST port line %d\n", port->line);

           state = drv->state + port->line;

           mutex_lock(&port_mutex);
           mutex_lock(&state->mutex);

and tell me what you get? You have to recompile the kernel...

Ciao,

Rodolfo
