Hi, I installed the 2.6.19-rc3 bits, and when I try to run perftest/rdma_bw (with '-c' option), I get the error : "librdmacm: Couldnt open rdma_cm ABI version". I found that this is due to ucma not being present in mainline kernel bits (which creates /sys/class/misc/rdma_cm). So how can I resolve this and run these tests ? Thanks, - KK
