I have an AX8817X based USB ethernet adaptor connected to it (it's short on PCI slots), so I compiled the usbnet module. When I loaded usbnet, I got a BUG at include/asm-generic/dma-mapping.h:19. Apparently, DMA setup only works with PCI here. How should this be fixed? It worked with -test4, albeit slowly, for other reasons. -- Måns Rullgård mru@users.sf.net
