Doc Text:
kdump uses the "crashkernel=" kernel parameter to reserve memory for the crash kernel. Previously, the sample grub.conf file provided in the kexec-kdump-howto.txt omitted this parameter. Users could not successfully modify grub.conf to boot a crashdump kernel using this documentation. The sample file now contains the correct kernel parameter and therefore describes a correctly configured grub.conf.

documentation fix

Description of problem:
While reviewing the documentation changes stemming from bug 510816 I noticed that the grub example in kexec-kdump-howto.txt is incomplete:

-----
Examples:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz

title Red Hat Enterprise Linux (2.6.18-8.el5)
        root (hd0,0)
        kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/VolGroup00/LogVol00
        initrd /initrd-2.6.18-8.el5.img

It's missing the crashkernel= directive ... patch attached.
