[openib-general] openib and mellanox hca problem

[Michael Di Domenico]

I'm trying to build a system using the openib drivers with a mellanox
hca card.  I don't have much information about the card itself, it's
in a server right now...

But I downloaded openib today from the svn source, installed it onto a
fresh copy of Fedora Core 4 with Kernel version 2.6.15.3... 
Everything seemed to compile fine and install okay.  I've been
following the instructions from the wiki page thus far without a
problem.  I get upto this step

modprobe ib_mthca

and get the below error in /var/log/messages.  Strangely enough all
the modules load, and i do a udevstart, but i never get a
/dev/infiniband directory and /sys/class/infiniband directory is
empty.

Does anyone know how i might fix this, or point me to some better
documentation then what is on the wiki?

Thanks
- Michael
