Dear experts,<br><br> First I don't know if I am posting in the right mailing list, if not, please apologize and let me know.<br><br><div class="gmail_quote">Here is my problem:<br>I am running a mandriva cluster ( Mandriva 2010.0 kernel 2.6.31.12), with a bunch of mellanox cards. I struggled during one week but finally I was able to install OFED 1.5.1 on my running kernel 2.6.31.12 (linux kernel provided by the mandriva distribution) and now it works very well and fast !<br>
<br>Recently I upgraded a part of my cluster with the latest stable kernel 2.6.32.27 downloaded from <a href="http://www.kernel.org" target="_blank">http://www.kernel.org</a>.<br><br>So far, I am not able to build the ofa_kernel from OFED 1.5.1 package for the kernel 2.6.32.27.<br>
<br>When I tried to rebuild the RPM, it stops with the following message :<br><br>-------------------------------------------------------------------------------------------------------------------------------------------------<br>

<br><br>RPM build errors:<br> Bad exit status from /var/tmp/rpm-tmp.Shec49 (%install)<br><br>-------------------------------------------------------------------------------------------------------------------------------------------------<br>
<br> According to the output, there are some unresolved symbols which I don't understand.... It looks like I get this unresolved symbols, **only** if I am using a linux kernel that I manually compiled. If I used a kernel provided by my distribution, these unresolved symbols vanished.... <br>
What I am doing wrong ? Is there specifics options to set when we compile the linux kernel from sources ?<br><br> Thanks in advance for your help.<br><br> Jean-Charles.<br><br>
