When I'm on the Xen kernel (with 4.0.1 en 4.1.3 version of Xen)

I have this problem on the log with "ib_umad" module

Dec 18 13:16:33 blade4 kernel: [  133.118783] user_mad: process ibsrpdm did not enable P_Key index support.
Dec 18 13:16:33 blade4 kernel: [  133.118787] user_mad:   Documentation/infiniband/user_mad.txt has info on the new ABI.

The command "ibsrpdm -c"  is not responding

And the status of the infiniband is :
