After looking through the logs again it appears this may be an Arm related problem. The dmabounce message is saying there is a device on the pci bus and then the drivers attach. When it fails the dmabounce message is coming after the usb drivers have attached to the device. Anyway I am posting this problem over to the arm-kernel list as well.
