RHBA-2012:0892 - Bug Fix Advisory

Topic

Updated grub packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

Description

The GRUB utility is responsible for booting the operating system kernel.

This update fixes the following bug:

• Due to an error in the underlying source code, previous versions of GRUB

sometimes failed to boot in Unified Extensible Firmware Interface (UEFI) mode
when booting from the network on systems with multiple Pre-boot Execution
Environment (PXE) network interface cards (NICs). This update ensures that GRUB
attempts to identify and use an active interface that has already successfully
acquired an address via Dynamic Host Configuration Protocol (DHCP) instead of
using the one suggested by the system. As a result, booting from the network in
UEFI mode now works as expected on systems with multiple NICs. (BZ#670266)

All users of GRUB are advised to upgrade to these updated packages, which fix
this bug.

Solution

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
