[lustre-discuss] Unknown symbol errors on client

[Andrus, Brian Contractor]

All,

I am seeing the odd Unknown Symbol errors on some of my client nodes when they boot up. It causes the system to take a LONG time to boot and I am trying to figure a cause.
I am confused a bit because I have 5 systems that are the same hardware. 2 of those systems boot up quickly, without the error.
Has anyone seen this on a client node? If so, what can be done to alleviate it?

At bootup, I see a line:
modprobe: FATAL: Error inserting lustre (/lib/modules/2.6.32-642.6.2.el6.x86_64/extra/lustre-client/fs/lustre.ko): Unknown symbol in module, or unknown parameter (see dmesg)

And I find in dmesg:
