RHBA-2012:0892 - grub bug fix update

Synopsis

grub bug fix update

Type/Severity

Bug Fix Advisory (none)

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.
