    Well, I have reproduced it with gregkh-usb-usbcore-remove-usb_suspend_root_hub.patch
    reverted too.

    Attached is the output of dmesg from the failing case with USB_DEBUG set.
    It covers two attempts to suspend to disk, the second one being unsuccessful,
    with reloading the ohci_hcd module in between. [This kernel also has your
    other patch to prevent the second suspend from failing applied, but it doesn't
    help.]

    Greetings,
    Rafael
