Only machines with this configuration on subnet getting this kind of packet loss. All other machines at zero packet loss including Sun 4500 running Sun Gigabit with no issues. Machines with exact configuration as above with standard 10/100 have no packet loss. Tried multiple configurations for driver options with very little success. Any ideas?
