<br><font size=2 face="sans-serif">We saw an error on Galaxy adapter while
ib_mad fails to create QP1 for the second port, then the first port becomes
useless. </font>
<br><font size=2 face="sans-serif">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. </font>
<br>
<br><font size=2 face="sans-serif">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.</font>

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