Description of problem:

The attached program cannot find any running IB devices, even though devices are running on the system.  I think I loaded the relevant drivers (why don't they automatically load?).

Version-Release number of selected component (if applicable):

list of installed RPMs is in attachment.

How reproducible:

Very

Steps to Reproduce:
1. Bring up Infiniband interfaces, including subnet manager and IP interface, verify that these work as expected
2. try running the simple program in attachment that searches for IB devices
  
Actual results:

It finds no devices, program is attached:

[root@perf56 ~]# ./ibvls 
libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs1
libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs0
ibv_get_device_list: list=0x1f08040 num_hcas=0
[

Expected results:

It should find every active IB interface.

Additional info:

I found this while trying to configure Gluster to use RDMA over this release, I'll fall back to 6.1 and see if it happens there.  The attachment contains these files:

sys-class-infiniband-verbs.log -- output of ls -l on /sys/class/infiniband_verbs/*
rpms.log -- rpm -qa output
ibvls.c -- program to scan list of Infiniband devices usinb libibverbs
ib0.log -- interface was up and running
lsmod.log -- what drivers were loaded when test was run
