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

[Pradeep Satyanarayana]

I was encountering some similar problems in the past and I put an entry 
into /etc/hotplug/blaclist like the following:

# Mellanox InfiniBand
ib_mthca

This has worked for me.

[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?
