Memory for crashkernel notwithin permissible range


I've installed LINUX for the very first time and when i rebooted it, i found this message on my screen "Memory for crashkernel notwithin permissible range"
I tried all my attempt like given memory to kernel with this command
"crashkernel=64M@16M" but no luck...
Finally i tried to boot into single user mode might be it helped me..but same results
Can anyone pls suggest me where exactly i'm lacking?

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:
http://wiki.centos.org/Manuals/Relea...efc2bde261b0a6
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:
http://www.centos.org/modules/newbb/...topic_id=11736
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.

Thank you for your quick response!
I'm using Red Hat Distro. How can i avoid this error?
Whenever I'm rebooting my system i got this error and everything stops here.
I searched in your mentioned links but not found any thing beneficial.
Pls suggest!

Repairing that on CentOS should be comparable to fixing it on RH. There's very nice instructional page here:
http://www.mjmwired.net/kernel/Documentation/kdump/

If you don't want to (or don't care to) configure it to work properly, it seems the next solution is to install a different kernel which does not have kdump enabled.

I don't use this kdump/kexec stuff myself, so that's the best I can provide -- you'll have to read and understand those instructions, and apply that information & knowledge to your system.
