 I can confirm that, I had the same problem with nve on 6.2-PRERELEASE
 and up-to-date 6-STABLE. Plugged fxp and it works like a charm now.

 I may be seeing the same problem on 6.3-RELEASE.  I can consistently cause a 
 reboot by running an rsync backup over nfs.  Popped in a Netgear card (dc 
 driver) and all is well.

 Just to be thorough, I'm going to do a minimal 7.0 install on a spare 
 disk, pop it into one of of the problem machines, and run an rsync over 
 NFS with the nfe driver.
 
 I'll get back to you ASAP.

 Thanks.  We should probably add a warning to the nve manpage and/or 
 GENERIC that it has known bugs.

 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.

 There was probably an update from the vendor in that timeframe that 
 introduced the bug.  nve is third party binary code with a FreeBSD 
 wrapper so we have limited ability to fix problems.

 I booted one of my problem children from a 7.0 disk, hammered the 
 network in both directions to/from an NFS server for nearly an hour.  
 Not a hiccup.  The nfe driver looks pretty solid from where I'm standing.

State-Changed-Why:  
Close, nve(4) used binary blob which made hard to fix the issue. 
nfe(4) was already back ported to stable/6 so you can still use 
nfe(4) instead of nve(4). If you still see issues on nfe(4) please 
open new PR. 
Anyway, thanks for reporting!
