Short of uninstalling the OFED-1.0 release, how can I stop the Infiniband
related kernel modules from loading at system boot? </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
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.</font><font size=3>

I used "/sbin/chkconfig" to turn off the "openibd"
and "opensmd" services in the </font><tt><font size=2>/etc/rc.d/</font></tt><font size=2 face="sans-serif">
runlevel files. I even removed "ifcfg-ib0" and "ifcfg-ib1"
from the </font><tt><font size=2>/etc/sysconfig/networking-scripts</font></tt><font size=2 face="sans-serif">
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:</font><font size=3> <br>

What have I missed?</font><font size=3> <br>
