Fixed In Version: irqbalance-1.0.4-7.el6_5
Doc Type: Bug Fix
Doc Text:
Previously, the irqbalance daemon did not consider the NUMA node assignment for an IRQ (interrupt request) for the banned CPU set. Consequently, irqbalance set the affinity incorrectly when the IRQBALANCE_BANNED_IRQS variable was set to a single CPU. In addition, IRQs could not be assigned to a node that had no eligible CPUs. Node assignment has been restricted to nodes that have eligible CPUs as defined by the unbanned_cpus bitmask, thus fixing the bug. As a result, irqbalance now sets affinity properly, and IRQs are assigned to the respective nodes correctly.
