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.
