This looks like an interrupt routing problem.

Initializing the QP table is the first time the driver tries to
execute a FW command and get a completion interrupt.  It seems the
driver never see the interrupt and eventually times out (should be a 1
minute timeout).

Do other drivers work on this system?  With this kernel?  If so what
IRQ do they assign to the HCA (it's shown in /proc/interrupts after
the driver is loaded).

Thanks,
 Roland
