Actually I just tried with ofed 1.4 and still see the problem :( I think I installed it correctly with a 2.6.26.2 kernel although I see the warning: libibverbs: Warning: couldn't load driver 'mthca': libmthca-rdmav2.so: cannot open shared object file: No such file or directory A small example using RDMA read is working. I just wanted to see if the problem exists with 1.4 even if it is a RC. Probably I will install 1.3.1 when I solve this problem.
