Try to study fault-injection. It's documented in
Documentation/fault-injection.txt inside kernel source tree.
Never use
it 'til now, so I only can give you a clue.
Thanks -
But this steps involves in kernel space,
I am looking for producing kernel panic/crash/hang by running some
script/application in user space - Is there any tool/standard

Why do you feel that you would be able to achieve this? Don't you
think that such scripts would then we used as a malware.
I think in order to have such a protection we have a user space and a
kernel space. You can panic/hang user space processes using user
space programs unless you have a loop hole in the kernel
implementation. Which no one will put intentionally.
You are exactly correct. I want to check whether my kernel is stable
or it is having any loop holes left. I hope this types of test should
be conducted by the kernel testers/Linux distribution Maintainer as a
routine test. to check whether their system is stable with the kernel.
you can try this out.
