So we discover the same devices twice? Can this be a reason for the hang? I guess in 2.6.25, the warning is gone with: commit fd7d1ced29e5beb88c9068801da7a362606d8273 Author: Greg Kroah-Hartman <gregkh@xxxxxxx> Date: Tue May 22 22:47:54 2007 -0400 PCI: make pci_bus a struct device This moves the pci_bus class device to be a real struct device and at the same time, place it in the device tree in the correct location. Note, the old "bridge" symlink is now gone.
