Details

Updated irqbalance packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

The irqbalance packages provide a daemon that evenly distributes interrupt
request (IRQ) load across multiple CPUs for enhanced performance.

This update fixes the following bugs:

* 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. (BZ#1054591)

* Prior to this update, the dependency of the irqbalance daemon was set
incorrectly referring to a wrong kernel version. As a consequence, irqbalance
could not balance IRQs on NUMA systems. With this update, the dependency has
been fixed, and IRQs are now balanced correctly on NUMA systems.

Note that users of irqbalance packages have to update kernel to 2.6.32-358.2.1
or later in order to use the irqbalance daemon in correct manner. (BZ#1055574)

Users of irqbalance are advised to upgrade to these updated packages, which fix
these bugs.
