I agree that is a complex problem with a non obvious solution, I have also used many re cards successfully and others not, but surely it's not a NFS issue. I can tell you more, I've used successfully a re card for years, and started seeing issues with the same card after upgrading my upstream connection to gigabit. The only thing that link all bug reports (and there are tons) is the use of re card sustaining gigabit (duplex) transfers. And I couldn't find similar reports for other chipsets that might lead to think it's a generic FreeBSD issue. Everything is possible, but the main suspect is the re driver. -- Alex Dupre
