I have to say I really haven't had this problem, even when running triple digit numbers of systems I can't think of the last time i've had an RHEL update go bad, kernel or otherwise.
Redhat took all of the upstream nfs client "fixes" that google primarily wrote and backported them to RHEL4. It did not go so well. The best thing I got out of working on this bug was ninja-level nfs debugging experience. See comment 8 for the secret sauce.

NFS client patches that google wrote?
Are you confusing google (no interest in NFS) with NetApp which employs Trond, the upstream client maintainer?
