So what is the actual version of the kernel you are running?

What was the purpose of this?  Generally speaking modules from one
kernel are not usable in other kernels.  I assume since you installed
lustre-client-modules-1.8.2-2.6.18_164.11.1.el5_lustre.1.8.2.x86_64.rpm
that you are using the RH kernel versioned 2.6.18_164.11.1.el5, yes?

You have a mismatch between the lustre modules you are using and the
kernel.

Right.  This was OFED 1.4.2 from the OFA.

Yes, in 1.8.2 we are using the OFED stack as shipped by RedHat which is
a 1.4[.1rc3 IIRC] stack.
