Could be some sort of timing bug in the NFS server code?

NFS 3

It could be anything, but I am more inclined to blame the client, as

1) Many clients work just fine
2) Even my bad desktop works fine when it connects after a reboot

Does it matter if it is a soft or hard mount?

I'm just guessing here. I've a long mount option string on my server:

eustorage:/opt /opt nfs rw,nodev,noatime,nfsvers=3,timeo=110,retrans=
50,hard,intr,proto=udp,rsize=32768,wsize=32768 0 0

But I'd be hard pressed to explain why I chose each option that I have in
there. :)

I had a problem with slackware-13.1 where I needed to add vers=3 to
stop the default nfs4 client throwing an error, worth a try?

deltree:/home/common /home/common nfs hard,intr,vers=3
deltree:/home/mirror /home/mirror nfs noauto,user,hard,intr,vers=3
