Details

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

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 used the IRQ handler names from the
/proc/interrupts file to decide the source class, which caused irqbalance to not
recognize network interrupts correctly. As a consequence, systems using
biosdevname NIC naming did not have their hardware interrupts distributed and
pinned as expected. With this update, the device classification mechanism has
been improved, and so ensures a better interrupts distribution. (BZ#817873)

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.
