Have you tried rebooting the switch acting as a router. In my experience about 20% of the boxes we enabled jumbo routing on would not work quite right until after a reboot. This is something that was solved by just reloading the switch after configuring the routing mtu in addition to the reload after configuring the layer2 mtu.
