Hi Kaushik,

Seems that you have an IRQ assignment problem which isn't the HSF
driver's fault. Try upgrading to the latest SuSE kernel, adding the
pci=biosirq parameter when booting, playing with ACPI BIOS settings,
and if everything fails you might have to compile the newest kernel
from ftp.kernel.org with the latest ACPI patches.

Let us know what worked..
