Well, it says to check dmesg... Though that will just list the
symbols. In general, this usually means you've got a mismatch
between the version of the kernel (or OFED) Lustre is built against
and your version of either the kernel or OFED. Given the number and
locations of the mismatches, I'm guessing it's the kernel.<br>
<br>
So, compare your kernel version and your Lustre RPMs.<br>
