<br>
The short answer is that you should use the 2.6.26 lenny kernel +<br>
ofa-kernel modules + the userspace packages.<br>
<br>
If you step outside that combination, you run the risk of things breaking.<br>
<br>
The OFED 1.4.X ofa-kernel modules only supports kernel versions up to<br>
2.6.26; if you are using a later kernel you will need to use the<br>
infiniband drivers included in the vanilla kernel tree.<br>
<br>
However, the vanilla kernel infiniband modules do not yet contain some<br>
of the features that included in OFED ofa-kernel modules (eg XRC). If<br>
you use the vanilla kernel modules you might find that some of the<br>
userspace utilities breaks.<br>
