Great, thanks for this note!
I've been struggeling quite a bit myself with Rocks-3.3 on opteron
(IBM e326), with AIX as file-server. I still don't quite understand
exactly what caused my hangs, but after reverting back to udp, and
default mount options plus increasing the number of lock-daemons on
the AIX-server, I now have a stable NFS. Still struggeling a bit with
the NFS performance..
Should maybe test if bcm lets me go back to nfs over tcp.

Maybe someone should do a kernel-2.6 roll for Rocks...
