Are you think of this quirk:

I looked at the sources and found your me_wifi_quirk() stuff.

But if I understand the code right, the patch doesn't help.

# lspci -n -s 00:00.0

00:00.0 0600: 8086:0044 (rev 02)

So IS_ILK(id) should be true.

But my WLAN adapter is:

10:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

# lspci -n -s 10:00.0

10:00.0 0280: 8086:422c (rev 35)

And the id 8086:422c is not in your switch statement and therewith

map_me_phantom_function() is not called.

By the way I don't see a pci device 0:22.7

It's a Fujitsu Lifebook S760

Following the intel spec I checked the device id of the D31:F0 device function:

00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC Interface Controller (rev 05)

# lspci -n -s 00:1f.0

00:1f.0 0601: 8086:3b07 (rev 05)

And this is the Intel® QM57 Chipset.

Thanks.

Dietmar.
