[openfabrics-ewg] [openib-general] Stopping Infiniband kernel modules from loading at system boot

[Boris Shpolyansky]

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?
