All, I have had to add the following to /etc/modules to get the network and usb controller to come up mvmdio mv643xx_eth ehci-orion Don't expect usb hotplug to work... AND if you were using UUIDs for disk mounts then you will need to change that back to devices as well none of disk/by-uuid, disk\by-path etc are generated. I have compared the rules.d to an independent one on a working armhf platform and there are no differences. I am running on the 3.16.0-4-kirkwood kernel which appears not to use DTBs so it is not related Iain |
