    Hal> The management class for the ping registrations (for the
    Hal> server) is not 0 so you can't run both kernel and usermode
    Hal> ibping server simultaneously.

But how did you run the kernel server and the user client at the same
time?  It seems they would have to register an agent for the same class.

    Hal> It looks right. Have you tried it out ?

Yes.

    Hal> Also, there was a thread a while ago on adding async event
    Hal> support to user_mad.c. This is needed by OpenSM. Any comments
    Hal> on this ?

I would prefer to leave the passing of async events to uverbs.
