Years ago when we had a serious NFS problem in RHEL 5, we had a support case
open with our TAM. If I remember correctly, it was Steve Grubb (kernel
engineer) who helped us narrow down the problem and get it fixed. If you can,
try using the same route. Open a high-priority case and get it escalated to a
kernel engineer ASAP, specifically a kernel engineer versed in the NFS code.
