Turns out that when you build your patched kernel, you DO NOT want to
change the EXTRAVERSION string in the Makefile such that it does not
include ".el5." somewhere in the string. If you do that, some of
the OFED configure scripts pick some patch files that are for a
different (vanilla) kernel. So once we put ".el5." back into our
version string, things worked as expected.
It sure seems like we should be able to set "EXTRAVERSION" to
anything we want without breaking builds i.e., there should be a more
reliable way of figuring out which kernel you are building against.
Sigh,

We seemed to have it a stumbling block when building with the above
(supported) versions. Our process...
1. Start with stock rhel5 2.6.18-8.1.14 source tree
2. Configure InfiniBand support out of the the kernel (we will build
OFED separately).
3. Apply the 1.6.4.2 kernel patches to the kernel source.
4. Build the kernel.
5. Build OFED 1.2 against the patched kernel
6. Build Lustre using the patched Kernel+OFED 1.2
This worked fine for 1.6.3 but for 1.6.4.2, after patching the kernel
and trying to build OFED 1.2, we get the error below. Now, we find
references to this problem all over the place but nothing specific to
building lustre. Since Lustre 1.6.4.2 is supposed to support OFED
1.2, it seems that OFED should build against a kernel patched for
lustre 1.6.4.2 but apparently it does not. If we use the un-
patched kernel (i.e. do not apply the lustre 1.6.4.2 kernel patches
to it), OFED 1.2 builds without a problem. We are looking for an
easy #define way out of this hole right now but if there is a known
solution to this, we would love to know about it.
If there is a better way to do this, we are open to that as well.
Thanks,
