In the short term, the solution to your problem is to patch your copy of the fxp driver so that this chip is treated like an older model. If you can't do that, then change your NFS mount options to use TCP, which will avoid the packet fragmentation. We already use TCP for the NFS mounts and I still see the exact same problems Matt
