Topic

Updated irqbalance packages that fix one bug are now available for Red Hat
Enterprise Linux 6.

Description

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

This update fixes the following bug:

  • The irqbalance daemon assigns each interrupt source in the system to a

"class", which represents the type of the device (for example Networking,
Storage or Media). Previously, irqbalance had some problems while classifying
certain NIC devices that resulted into performance impact on affected systems.
With this update, the NIC classification mechanism has been updated to work with
all types of NICs. (BZ#845374)

All users of irqbalance are advised to upgrade to these updated packages, which
fix this bug.

Solution

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat
Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
