<DIV><SPAN class=017095217-23062006><FONT face=Arial color=#0000ff size=2>I
believe you need to disable the "hotplug" loading of the Infiniband
drivers</FONT></SPAN></DIV>
<DIV><SPAN class=017095217-23062006><FONT face=Arial color=#0000ff size=2>by
putting the modules you have listed into /etc/hotplug/blacklist
file.</FONT></SPAN></DIV>

Infiniband kernel modules from loading at system boot<BR></FONT><BR></DIV>
<DIV></DIV><BR><FONT face=sans-serif size=2>Short of uninstalling the OFED-1.0
release, how can I stop the Infiniband related kernel modules from loading
at system boot? </FONT><BR><BR><FONT face=sans-serif size=2>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> <BR><BR><FONT face=sans-serif size=2> I
used "/sbin/chkconfig" to turn off the "openibd" and "opensmd" services in
the </FONT><FONT size=2><TT>/etc/rc.d/</TT></FONT><FONT face=sans-serif size=2>
runlevel files. I even removed "ifcfg-ib0" and "ifcfg-ib1" from the
</FONT><FONT size=2><TT>/etc/sysconfig/networking-scripts</TT></FONT><FONT
face=sans-serif size=2> 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> <BR><BR><FONT
