One other thing, that you may already be aware of: The problems seem to
have started with FreeBSD 6.2. I have a couple of PC-BSD 1.3 (FreeBSD
6.1) workstations, and a FreeBSD 6.1-AMD64 RAID backup server that use
nve with no problems. The RAID server backs up about 40 workstations
every night using rsync, mostly over NFS.
