What I did is adding this line to drivers/serial/serial_cs.c line 241:

printk(KERN_NOTICE "serial_cs, debug prinkt 1\n");

Which makes:

static dev_link_t *serial_attach(void)
{
        struct serial_info *info;
        client_reg_t client_reg;
        dev_link_t *link;
        int ret;

        DEBUG(0, "serial_attach()\n");
        printk(KERN_NOTICE "serial_cs, debug prinkt 1\n");

        /* Create new serial device */
        info = kmalloc(sizeof (*info), GFP_KERNEL);
        if (!info)
                return NULL;
        memset(info, 0, sizeof (*info));
        link = &info->link;
        link->priv = info;

Is that correct? Nothing turns up in dmesg.
Should I place more of them elsewere?

Btw, I have CONFIG_PCMCIA_DEBUG=y so I assume the "serial_attach()\n"
should have been printed anyway.

What I have now is (2.6.14-mm2):

(ttyS0 is the onboard serial port, which shows up before I
do pcmcia-socket-startup and modprobe.

Anything I can do?

Thanks!
