In fact, this is how I know it when hot plug works. On ubuntu 9.10 and centos 5.4, the dmesg shows nothing while in FC12, it shows messages like [265565.693825] pci 0000:00:06.0: reg 10 io port: [0x00-0x3f] [265565.694573] pci 0000:00:02.0: BAR 6: bogus alignment [0x0-0x0] flags 0x2 [265565.694640] decode_hpp: Could not get hotplug parameters.
