Hello Vasily,

Replacing the kernel on the initiator system is sufficient. You don't 
have to replace the kernel on the target system for this test. Regarding 
which InfiniBand stack to use at the initiator side in combination with 
kernel 3.6: unless there is something I do not yet know about, it is 
fine to use the InfiniBand stack included in that kernel and it is not 
necessary to install OFED for this test.

Bart.
