What is a kernel Panic?

It is an action taken by linux kernel when it experiences a situation from where it can't recover safely.In many cases the system may keep on running but due to security risk by fearing security breach the kernel reboots or instructs to be rebooted manually.

It can be caused due to various reasons-
1. Hardware failure
2. Software bus in the OS.
3. During booting the kernel panic can happen due to one of the reasons-
a.Kernel not correctly configured, compiled or installed.
b.Incompatibility of OS, hardware failure including RAM.
c.Missing device driver
d.Kernel unable to locate root file system
e.After booting if init process dies.

In windows operating systems the equivalent term is stop error(or, colloquiaally Blue screen of death).

For any clarifications or if you have any suggestion please post comments below.
