    The reason for this error is that the root hub wasn't already
    suspended. Was there a USB device plugged into that controller?

    Two days ago I ran 2.6.27-rc6 plus gregkh-all-2.6.27-rc6.patch from

    http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/

    on my laptop, and it suspended with no problem. Can you try the same
    kernel?

    If you still run into problems, post more of the dmesg log (with
    CONFIG_USB_DEBUG enabled, of course!).
