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.]
