That is a possibility. I'll see if I can get a new kernel for one of the =

RHEL systems. Since my company wants all systems to be at the same rev,=20
it requires a bit of politicking. I would love to be able to upgrade my=20
IA64 system, but the latest IA64 release is Fedora9 which has the same=20
problem. Unfortunately, the reason they don't have the problem in=20
Toronto is that the main cluster uses Solaris as the NFS server, and my=20
group's cluster is using RHEL 3 for the NFS server. The reason we don't=20
want to downgrade is that the NFS server we are using is also a=20
development machine.
