    The commit that resulted in the messages disappearing was:
    commit a76117dfd687ec4be0a9a05214f3009cc5f73a42
    Author: Matthew Wilcox <willy@linux.intel.com>
    Date: Wed Jun 17 16:33:35 2009 -0400
    x86: Use pci_claim_resource

    The commit that caused the messages to return is:
    commit 79896cf42f6a96d7e14f2dc3473443d68d74031d
    Author: Linus Torvalds <torvalds@linux-foundation.org>
    Date: Sun Aug 2 14:04:19 2009 -0700
    Make pci_claim_resource() use request_resource() rather than insert_resource()

    The affected devices are the two USB UHCI controllers.

    Cheers,
