No kdump initial ramdisk found.

[Tanweer Noor]

did you reboot system? if not, please do so. then check whether the system
is already generating a vmcore. Look on the console (either at the machine
directly, or through a kvm or serial console interface). If kdump is already
running, just wait for it to finish.
 If kdump is not running, you can start it by pressing Alt + SysRq
(PrintScreen) + C. This will instruct the kernel to panic and generate a
vmcore.
