[openib-general] OpenSM causes kernel trap

[Jay Higley]

I am trying to start up opensm on a Dell PowerEdge 2850 with a Mellanox 
based infiniband card.  We are using the x86-64 Architecture.  The 
kernel is recompiled with the latest stack from subversion, and all of 
the modules load OK.  However, when I try to start opensm I get the 
following error.  After this, then modules can not be successfully 
removed from the kernel and opensm is not successfully running.  I can 
send the output from opensm's log file if anyone is interested.  Thanks.
