Luca, I've had the same issue with this interface on both PCIe boards and embedded in a handful of Lenovo products. The one, fairly ugly workaround I've found that makes it work well enough is disable tso ( i.e. ifconfig re0 down && ifconfig re0 -tso && ifconfig re0 up ). This also seems to stop the panics under current. I'm not sure it will work for you - but it has on everyone of those interfaces I've dealt with.
