We saw an error on Galaxy adapter while ib_mad fails to create QP1 for the second port, then the first port becomes useless.
The right behavior shouldn't prevent port1 from working. Second if loading ib_ipoib module afterwards, and configure the ib interface, the kernel will hung and oops. Simpling add a port_usable[] field in ib_device will address this problem.
After connecting the IB cable to port1, the port status changes from DOWN to ACTIVE. The QP1 creation would be successful if in the async event checking the port_usable[port_num] and calling mad_port_open() and agent_port_open() for that particular port. I haven't tested this out yet.

I don't think that matters. What is the initialization failure that is
occurring ? Any error message ?
