RHBA-2011:1224 - Bug Fix Advisory

Topic

An updated cpufrequtils package that fixes a bug is now available for Red Hat
Enterprise Linux 6.

Description

The cpufrequtils package contains utilities that can be used to control the
cpufreq interface provided by the kernel on hardware that supports CPU frequency
scaling.

This updated cpufrequtils package fixes the following bug:

• Prior to this update, the cpufreq-aperf utility did not run on 32-bit systems

due to an incorrect argument passed to the read() call. This problem has been
fixed: the buffer size is now used instead of the size of the pointer and the
cpufreq-aperf utility runs as expected. (BZ#675734)

All users of cpufrequtils are advised to upgrade to this updated package, which
resolves this bug.

Solution

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