After all sorts of debugging didn't really bring any insight what the issue is, a reload of the linecard to GEANT helped to solve the problem. The theory is that an FPD upgrade of the linecard firmware needed another reboot for the linecard to be compatible with the new software version.

The router CE1 came back up after the upgrade, unfortunately the 100G link to GEANT does not work properly yet, we can't ping the neighbor routers.
no ETR yet.
