Clearfog Pro: lan1-lan6 broken after upgrade

I am running a clearfog pro which works fine with openwrt 17.06
I made an update image and flashed the firmware - compared the both .configs with kdiff.
After flashing the firmware, lan1-lan6 are broken - they are not recognized. Anyone here with the same problem?

Can you verify that you built your image for the ClearFog Pro and not the ClearFog Base? The Base does not have the switch therefore the device-tree is different and omits the switch.

Yes, i built the version for the pro and not the base.
