[nsp] CEF problem on 6509 (native)

One of our Cat6500 routers' CEF is acting strangely. The router wouldn't
forward traffic towards x.y.z.25, but it would for x.y.z.26. CEF has an
entry for x.y.z/24 (known by the router from BGP).

If i put an ACL on a VLAN (in) with permit for x.y.z.25, traffic coming
via that vlan will be routed, but only the traffic coming via that vlan.

The temporary solution was to have a route for x.y.z.25.

The 6509 has msfc2/sup2, and runs Version 12.1(19)E (native). I looked for
CEF bugs using cisco's bugtool, but none match my case.

Does anybody have a clue on how to solve this problem?
