[Users] NFS with RHEL5 kernel?

[E Frank Ball]

I tried using the RHEL 5 kernel again
(ovzkernel-2.6.18-8.el5.028stab031.1.i686.rpm) and I still
can't get NFS to work.  I tried it without amd (the
automounter) this time.  I tried mounts from both HP-UX and
NAS servers.

I get a "mount:  permission denied" error, and this spews
onto the console:
