An updated cpufrequtils package that fixes a bug is now available for Red Hat Enterprise Linux 6.
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.
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.
All users of cpufrequtils are advised to upgrade to this updated package, which resolves this bug.
