Synopsis
irqbalance bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated irqbalance package that fixes various bugs is now available.
Description
irqbalance is a daemon that evenly distributes IRQ load across multiple
CPUs for enhanced performance.
This updated package addresses several minor bugs:
- multiple instances of irqbalance could be started when changing between
run levels. A universal exit is now run on existing instances so that only
one will operate at a time. (BZ#471574)
- several errors in set_interrupt_count and investigate interaction caused
irqbalance to ignore IRQBALANCE_BANNED_INTERRUPTS. The two now work
discretely and the problem no longer presents. (BZ#479459)
- documentation has been improved in order to clarify the meaning and use
of some of the configuration settings in irqbalance. (BZ#479856)
Users are advised to upgrade to this updated irqbalance package, which
resolves these issues.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
