description:
When detecting a new USB device on the bus ofppc panics in usb_allocmem().
Although the problem doesn't seem to affect other PPC ports, it causes big
trouble for my Pegasos2.
So as long as there is no real solution we should add the option
USB_FRAG_DMA_WORKAROUND to the GENERIC config file.
