kexec/kdump problems


Hi,
I'm trying to use kdump on system panic, but facing some problems while loading the second kernel using kexec. Btw, Can i use the same kernel as both 1st and crash kernel? Im using 2.6.21 for both.

I have enabled all the config options involved in kexec and this is the outout while trying to load the crash kernel ( same kernel).


kexec -p /boot/vmlinuz-2.6.21 --append="root=LABEL=/ dump init 1 memmap=exactmap memmap=640k@0 memmap=32M@16M"
Could not find a free area of memory of 9000 bytes...
locate_hole failed


I booted the first kernel with the option crashkernel=64M@16M and couldn't find /proc/kexec-dump. Am i missing something?

Regards,
Gk
