irqbalance bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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

This update fixes the following bug:

• Previously, if a device disappeared and then reappeared, the "irq_count" interrupt request (IRQ) counter in irqbalance overflowed, which resulted in a failure to balance IRQs. This update adds a check which triggers a rescan of the IRQ database if the counter decreases. As a result, IRQs remain correctly balanced for disappearing and reappearing devices. (BZ#1541290)
  

Users of irqbalance are advised to upgrade to this updated package, which fixes this bug.

Solution

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