Fixed In Version: kexec-tools-1_102pre-126_el5_6_5 Doc Type: Bug Fix
Doc Text:
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.
