What kind of PCB are you using?
2- or 4-layers?
If you don't have an inner layer dedicated to ground and run all connections to gnd directly down to this plane you may have problems especially at high clock frequencies. This layer should have no traces so it is one continuous metal plane.
But I guess your board is not a simple 2-layer board, right?
