Hi Troy and Jarek,

I have now a FJS S7110 notebook for testing (see lspci -v below). It
comes with an Intel Core Duo CPU and ipw3945. I would be really glad to
see the ipw3945 working.

I could rebuild the kernel ipw3945 module without any problems - many
thanks to Jarek!

However, on this hardware ipw3945 still does not work. If I load the
module, I get the following error:

kernel: ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver
for Linux (with 80211 built-in), 1.1.0-pre2
kernel: ipw3945: Copyright(c) 2003-2006 Intel Corporation
kernel: ACPI: PCI interrupt 0000:05:00.0[A] -> GSI 18 (level, low) ->
IRQ 217
kernel: PCI: Unable to reserve mem region #1:d0100000@30000000 for
device 0000:05:00.0
kernel: ipw3945: probe of 0000:05:00.0 failed with error -16

I see the error on the latest SL4 kernel and as well on the latest SLC4
kernel.
I also took the latest ipw3945 version (1.1.0) - still the same problem.
With a 2.6.17 kernel running under SL4 ipw3945 works just without any
problem.

The problem seems to be a "memory conflict" between the ipw3945 and the
CardBus bridge (?)

I tried to boot with "noacpi", did not help. And a can not disable the
CardBus in the BIOS.
Have you seen this problem before? Any ideas?
