The short answer is that you should use the 2.6.26 lenny kernel +
ofa-kernel modules + the userspace packages.

If you step outside that combination, you run the risk of things breaking.

The OFED 1.4.X ofa-kernel modules only supports kernel versions up to
2.6.26; if you are using a later kernel you will need to use the
infiniband drivers included in the vanilla kernel tree.

However, the vanilla kernel infiniband modules do not yet contain some
of the features that included  in OFED ofa-kernel modules (eg XRC). If
you use the vanilla kernel modules you might find that some of the
userspace utilities breaks.

Cheers,

Guy
