Hi
Don,
I
believe you need to disable the "hotplug" loading of the Infiniband
drivers
by
putting the modules you have listed into /etc/hotplug/blacklist
file.
Please, let me know if this helped.

Subject: [openib-general] Stopping Infiniband kernel modules from loading at system boot
Short of uninstalling the OFED-1.0 release, how can I stop the Infiniband related kernel modules from loading at system boot?
I am trying to debug a problem with programs hanging in the kernel, so I thought that I would try manually loading the modules one at a time to see if I could isolate the problem. This is on a RHEL4 U3 system with the 2.6.16 kernel and the OFED-1.0 release installed.
I used "/sbin/chkconfig" to turn off the "openibd" and "opensmd" services in the /etc/rc.d/ runlevel files. I even removed "ifcfg-ib0" and "ifcfg-ib1" from the /etc/sysconfig/networking-scripts directory. I don't see any other scripts that would cause these modules to be loaded. But every time I reboot, I get the following modules loaded, according to /sbin/lsmod:
ib_mthca 117424 0
ib_mad 35896 1 ib_mthca
ib_core 45952 2 ib_mthca,ib_mad
What have I missed?
