Hi!

I'm trying to use Intel Wireless 2100 adapter on my centrino based
notebook. I use ipw2100 drivers from ipw2100.sf.net. The thing is that
hardware says that the device should generate irq11, but it really
generates irq5. I tryed both 2.4.26 and 2.6.5. I also tryed to compile
kernel with and without ACPI. I tryed to compile kernel with and
without APIC support. I also tryed to pass some parameters to kernel
(acpi=off, acpi=force, pci=biosirq). But anyway kernel says irq 11 and
device generates irq5. Of course it is possible to be hardware
problem, but it works under windows.

Any suggestions?

Here is information about the system:
