 I hope I'm doing the follow-up right; I don't know how to see
 follow-ups in GNATS.
 
 At work I tested a FreeBSD-4.9-PRERELEASE client against our netapp
 and found the same failure with the "nfstest" program Brian posted. A
 Solaris-2.9 client did not exhibit this problem.
 
 When I got home, I ran the test with a FreeBSD-5.1 client to NetApp,
 then with FreeBSD client to FreeBSD server.  Both failed the same
 way.  This would tend to indicate an NFS client problem in 4.x and
 5.x.
 
 
 NFS from FreeBSD-5.1-CURRENT client to NetApp-6.3.2 fails:

 NFS from (diskless) FreeBSD-5.1-CURRENT client to FreeBSD-5.1-CURRENT
 NFS server also fails:
