Two clients started showing the problem after
being upgraded from FC2 to FC3, while the server
remained unchanged.

Can you produce tcpdumps to back that up?

Neil's problem appeared rather to be server-related. Neither of us could
reproduce his problem when the server was exporting an XFS partition.

Actually, I was mistaken: running a background "find / >/dev/null"
triggers the problem even on the old RedHat (2.4.26) and
Gentoo (2.6.11) clients.

The other thing to try is to turn off subtree checking on the server.

It's already turned off on all shares. For the record, this is the
contents of my /etc/exportfs:

/home gss/krb5(rw,no_root_squash,no_subtree_check,async) beetle(rw,no_root_squash,no_subtree_check,async) deimos(rw,async,no_subtree_check,anonuid=134,anongid=100) haring(rw,async,no_subtree_check,anonuid=127,anongid=100) murphy(rw,async,no_subtree_check,anonuid=158,anongid=100) daneel(rw,async,no_subtree_check,anonuid=100,anongid=100),no_subtree_check,async)

# NFSv4
/export beetle(rw,fsid=0,no_root_squash,insecure,no_subtree_check,async)
/export gss/krb5(rw,fsid=0,insecure,no_subtree_check,async)
/export/home beetle(rw,nohide,no_root_squash,insecure,no_subtree_check,async)
/export/home gss/krb5(rw,nohide,no_root_squash,insecure,no_subtree_check,async)
