Try to study fault-injection. It's documented in

Never use

Thanks -
But this steps involves in kernel space,
I am looking for producing kernel panic/crash/hang by running some

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.

Sandeep.
