The cause of this problem might be an wrong assumption that the 'start'
member of resource structure for ioapic device has non-zero value if the
resources are assigned by firmware.  The 'start' member of ioapic device
seems not to be set even though the resources were actually assigned to
ioapic devices by firmware.
