Memory for crash kernel (0x0 to 0x0) not within permissable range
When booting Centos 5.5 on a vmbox running on windows XP I get the following message.
Memory for crash kernel (0x0 to 0x0) not within permissable range
By reading http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1
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.
This is for CentOS 5.1, you can assume it's valid for 5.5 too
