I don't see any reason probing of these two drivers should fail if there is no or reduced I/O space. Please can you share the kernel messages so we can see exactly what is failing and how? -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
