Yes, we've got consistent OFED-1.5.4 user-space. "ibv_devinfo" reports a "mismatch between the kernel and the userspace libraries" - "kernel does not support XRC.". "ibverbs-driver-mlx4" is at version 1.0.1-1.20.g6771d22 and "libibverbs" is at version 1.1.4-1.24.gb89d4d7. But O.K., the other method shows firmware version "2.9.1000". iSER only works on productive servers, because we use the OFA kernel modules from OFED for them at the moment (with 3.0 ported *iscsi* drivers). But there the IPoIB traffic is too slow for us. We connect customer VMs with IPv6 between different servers via IB. And yes, we could also test kernel 3.2 on our iSER test server.
