Problem with Sierra Wireless AC775 on PCIxx12 Cardbus Controller on x86_64

Hi.

Socket : yenta_socket / PCIxx12 (TI)

Problem seems to be with serial_cs.

Card is detected, and serial_cs loaded by udev, but never get the kernel 
message telling me serial port have been correctly established. I cannot 
access ttyS1 at all (pppd claims input/output error, as if there wasn't 
any device)

Here are more detailed information :

[here, I plug the card in]

[then, nothing more happen]

I would really like to help find the bug, but need some hints to know 
where to start. Where do I start putting printk's :-)

Many thanks for your help.
