During the boot process you may see the message "Memory for crash kernel (0x0 to 0x0) notwithin permissible range"
appear. This message comes from the new kdump infrastructure. It is a harmless message and can be safely ignored.
The above comes from here:
in the section called "Known Issues". I found that on the top of the first page returned by Google, when I searched for the Error Message you gave.
You may like to (and probably should) read all of that page, and this one too:
if you are using CentOS (or perhaps RHEL/RedHat too)
NOTE: You did not tell us what Linux distro you are running, so I took a wild guess, after using Google, that you are running CentOS. If this is wrong, please tell us what linux you are using.
