RHBA-2013:0584 - kernel bug fix update

Synopsis

kernel bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated kernel packages that fix two bugs are now available for Red Hat Enterprise Linux 6 Extended Update Support.

Description

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

This update also fixes the following bugs:

• Previously, NFS mounts failed against Microsoft Windows 8 servers, because the Windows server contained support for the minor version 1 (v4.1) of the NFS version 4 protocol only, along with support for versions 2 and 3. The lack of the minor version 0 (v4.0) support caused Red Hat Enterprise Linux 6 clients to fail instead of rolling back to version 3 as expected. This update fixes this bug and mounting an NFS export works as expected. (BZ#891862)

• If Time Stamp Counter (TSC) kHz calibration failed, usually on a Red Hat Enterprise Linux 6 virtual machine running inside of QEMU, the init_tsc_clocksource() function divided by zero. This was due to a missing check to verify if the tsc_khz variable is of a non-zero value. Consequently, booting the kernel on such a machine led to a kernel panic. This update adds the missing check to prevent this problem and TSC calibration functions normally. (BZ#905433)

Users should upgrade to these updated packages, which contain backported patches to fix these bugs. The system must be rebooted for this update to take effect.

Solution

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

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.
