1.75.1. RHBA-2011:0382: kexec-tools bug fix update
An updated kexec-tools package that fixes one bug is now available for Red Hat Enterprise Linux 5 Extended Update Support.
The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel. The kexec-tools package provides the /sbin/kexec binary and ancillary utilities that form the user-space component of the kernel's kexec feature.
* On certain hardware, the kexec kernel incorrectly attempted to use a reserved memory range, and failed to boot with an error. This update adapts the underlying source code to determine the size of a backup region dynamically. As a result, kexec no longer attempts to use the reserved memory range, and boots as expected. (BZ#682085
All users of kexec-tools are advised to upgrade to this updated package, which fixes this bug.
