RHBA-2010:0887 - Bug Fix Advisory

Topic

Updated kernel packages that resolve several issues are now available.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating
system.

These updated kernel packages provide fixes for the following bugs:

• This update introduces additional stack guard patches. (BZ#632514)
• Previously, a warning message was returned when a large amount of messages was

passed through netconsole and a considerable amount of network load was added.
With this update, the warning message is no longer displayed. (BZ#646760)

All users of kernel are advised to upgrade to these updated packages, which
resolve these issues.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red Hat
Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm

• Uvh" as that will remove the running kernel binaries from your system. You may

use "rpm -e" to remove old kernels after determining that the new kernel
functions properly on your system.
