I don't encounter this problem on the stock CentOS 4 kernel. The machine is a PowerEdge 2850 with 2 e1000 cards - the one in use is connected to a PowerConnect 2216 10/100 switch and has negotiated 100Mbit. I'll check if the stock Cambridge isn't negotiating full duplex but that shouldn't cause lockups. My mount options are: defaults,intr,rsize=3D32768,wsize=3D32768,nfsvers=3D3,tcp,timeo=3D600 This isn't at NetApp (no 100Mbit there), but these are the options used by all their linux NFS clients.
