[ltp] eSATA controller Express Card in ThinkPad T520 not working

[Martin Steigerwald]

Hi!

I bought a flat Delock eSATA controller Express Card in order to equip my=20
ThinkPad T520 with what should have been there as standard in the first=20
place[1] - an eSATA port than I can leave permanently installed.

Problem is: It is not recognized by the kernel in any way:

=2D nothing in syslog
=2D nothing in udevadm monitor
=2D nothing in lspci -tvnn

Whats up? Is it the card? Is it the Express Card slot? Is it the kernel=20
not knowing how to access the Express Card slot? Anyone with a T520,=20
please try to insert an Express Card and report here whether it works.

I am pretty sure that the Express Card had contact with the slot socket.=20
It got a bit warm after a while and it made a click when inserting it.=20
Also I tried several times.

I wondered whether the right Silicon Image driver is missing, but the=20
product page at Delock mentions Linux 2.6 as supported and I believe=20
whether a suitable module is there or not, udevadm monitor should at least=
=20
report a kernel event. Anyhow Delock support has confirmed that the card=20
works with a stock 2.6 kernel without any externally compiled drivers.

Is there anyway how I can check that the Linux kernel actually sees the=20
Express Card slot?

I did also recheck in the BIOS whether the slot is disabled, but it is=20
enabled. I didn=B4t change anything regarding I/O port access.
