One poster notes that he could transfer 300+GB of data error-free using rsync, but with NFS he encountered problesm after a few GB. To me this is an indictment of the NFS implementation used and not of the re driver itself. The same goes for some other posts. Everyone blames re, but AFAICT no-one switched to a non-Realtek chip to run tests and prove that, yes, re is really the cause of all the network problems. I've been using re for many years in various incarnations - PCIe cards and integrated on the mainboard. I've never experienced any network instabilities. But I've never used one in a NFS server under FBSD. I do, however, have one in a Linux NFS server (which was at one time my primary FBSD box) and never observed any problems. In summary, this is one tough nut to crack. -- Gary Jennejohn
