RHBA-2010:0776 - Bug Fix Advisory

Topic

An updated kexec-tools package that fixes a bug is now available.

Description

The kexec-tools package provides /sbin/kexec binary that facilitates a new
kernel to boot using the kernel's kexec feature either on a normal or a panic
reboot.

This updated kexec-tools package fixes the following bug:

• Previously, "/sbin/kexec" could run out of buffer on a PowerPC, when the

PowerPC's memory was large, due to the buffer size limit for devtree. This
caused kdump to fail to start. With this update, the buffer size is increased,
thus, segmentation faults no longer occur and kdump is able to start as
expected. (BZ#639303)

All users of kexec-tools are advised to upgrade to this updated package, which
resolves this issue.

Solution

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