But my doubt is that the PCI Express devices down the hot-pluggable slots are working fine. i.e. if we forget about the hot-plugging / unplugging, the bridges and devices are working fine, even with ACPI enabled. So is the presence of bridges in ACPI namespace required only for hot-plugging / unplugging and not for normal operation? Thanks, Rajat
