RHBA-2011:0502 - Bug Fix Advisory

Topic

An updated cpuspeed package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

Description

The cpuspeed daemon manages the CPU frequency scaling.

This update fixes the following bug:

• The /etc/sysconfig/cpuspeed configuration file allows a user to specify custom

maximum (the "MAX_SPEED" option) and minimum (the "MIN_SPEED" option) clock
speed limits. Prior to this update, when a user removed these custom settings
from the configuration and restarted the service, the cpuspeed init script
failed to reset these values to the hardware-specific limits. With this update,
the init script has been adapted to ensure that when the minimum or maximum
clock speed value is not specified, cpuspeed correctly uses the value reported
by the CPU. (BZ#616524)

All users of cpuspeed are advised to upgrade to this updated package, which
fixes this bug.

Solution

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