I run IMB exchange on two QS22 machines with r19674 and it got stucked after 256 or 512 bytes every time. After applying r19717 the test passed, so I guess this is a essential patch. This commit was SVN r19752. The following SVN revision numbers were found above: r19674 --> open-mpi/ompi@15c47a2473 r19717 --> open-mpi/ompi@0a765cd788
