[ADITYA KRISHNAN]

Hi,
I am new to crash utility. I want to run crash ( crash 4.0-2.18.1) on dual-core
AMD Opteron (x86_64) cluster. The cluster nodes are running xen 3.0 the
proc/version gives the following output : 2.6.16.13-xen
i am running xen 3.0 which has been installed on fc5.

I guess the kernel was not built with debugging info on

Running crash gives the following output:

crash 4.0-2.18.1

WARNING: cannot read linux_banner string
crash: /boot/vmlinux-syms-2.6.16.13-xen and /dev/mem do not match!

I read up on the previous threads that this is because /dev/mem returns all
zereos.
 I think I need something like a patch for installing the /dev/crash module.
I am new to this so can anyone help me out with a detailed procedure of what
needs to be done.

Thank You.

Aditya Krishnan
