This bug has been copied from bug #645547 and has been proposed to be backported to 5.5 z-stream (EUS).

New Contents: Previously, an attempt to connect to a target machine using the SCSI RDMA Protocol (SRP) could cause SCSI requests to fail with a timeout. When this happened, this error rendered mapping of SCSI over InfiniBand unusable. This update applies an upstream patch that resolves this issue, and the mapping of SCSI over InfiniBand now works as expected.
