I can confirm that I have exactly the same problem, also on Dell system, even with latest openpmpi.

Our system is:

Dell M905
OpenSUSE 11.1
kernel: 2.6.27.21-0.1-default
ofed-1.4-21.12 from SUSE repositories.
OpenMPI-1.3.2


But what I can also add, it not only affect openmpi, if this messages are triggered after mpirun: [node032][[9340,1],11][btl_openib_component.c:3002:poll_device] error polling HP CQ with -2 errno says Success

Then IB stack hangs. You cannot even reload it, have to reboot node.

Anton.
