Comment 9 for bug 394413

after upgrading to karmic (2.6.31-14-generic #48-Ubuntu SMP), then nfs problems are gone.

I have had good success with udp mounting using autofs.

mountname -rw,user,auto,rsize=16384,wsize=16384,timeo=60,intr 192.168.1.17:/mnt/raid1d1/media

works great. Autofs also unmounts them when not being used useful for not hogging up nfsd processes on the server.
