10 Gb link between 5406zl and 3500yl with lots of FCS errors

We have connected a 5406zl switch and a 3500yl switch using 10 Gb X2 ports using 10-GbE X2-SC LR optic gbics.
When traffic begins to flow i get lots of FCS errors on the receiving end of the 3500yl.
I have updated the software to K.14.41, I replaced the Gbics, I tested the fiber again (and it's OK) and still no change.
Does anybody have any ideas ?
