+When multiple InfiniBand HCA's are present in a target system the Linux
+kernel by default will assign the associated interrupt handlers to CPU 0.
+Even irqbalance will often assign the interrupt handlers of multiple HCA's
+to the same CPU. That is unfortunate because it leads to unfair handling of
+SRP sessions. The solution is to assign InfiniBand HCA interrupts manually

+interrupt numbers in /proc/interrupts and by writing proper bitmasks into
+/proc/irq/<n>/smp_affinity.
