systems; for Microsoft Windows operating systems the equivalent term is "Stop error" (resulting kernel panic causes in a "Stop error screen," or colloquially, a "Blue Screen of Death"). The kernel routines that handle panics, known as

panic() in AT&T-derived and BSD Unix source code, are generally designed to output an error message to the console, dump an image of kernel memory to disk for post-mortem debugging, and then either kernel panic windows wait for the system to be manually rebooted, or initiate an automatic reboot.[2] The information provided is of a highly technical nature and aims to assist a system administrator or software developer in diagnosing the problem. Kernel panics can also be caused by errors originating outside of kernel space. For example, many Unix OSes panic if the init process, which runs in userspace, terminates.[3][4] Contents kernel panic linux troubleshooting 1 History 2 Causes 3 Operating system specifics 3.1 Linux 3.2 OS X 4 See also 5 References History[edit] The Unix kernel maintains internal consistency and runtime correctness with assertions as the fault detection mechanism. The basic assumption is that the hardware and the software should perform correctly and a failure of an assertion results in a panic, i.e. a voluntary halt to all system activity.[5] The kernel panic was introduced in an early version of Unix and demonstrated a major difference between the design philosophies of Unix and its predecessor Multics. Multics developer Tom van Vleck recalls a discussion of this change with Unix developer Dennis Ritchie: I remarked to Dennis that easily half the code I was writing in Multics was error recovery code. He said, "We left all that stuff out. If there's an error, we have this routine called panic, and when it is called, the machine crashes, and you holler down the hall, 'Hey, reboot it.'"[6] The original panic() function was essentially unchanged from Fifth Edition UNIX to the VAX-based UNIX 32V and output only an error message with no other information, then dropped the system into an endless i

can no longer operate safely. In Microsoft Windows, a fatal system error can be deliberately caused from a kernel-mode driver with either the KeBugCheck or KeBugCheckEx function.[1] However, this https://en.wikipedia.org/wiki/Kernel_panic should only be done as a last option when a critical driver is corrupted and is impossible to recover. This design parallels that in OpenVMS. The Unix kernel panic concept is very similar. Overview[edit] When a bug check is issued, a crash dump file will be created if the system is configured to create them. This file contains a "snapshot" https://en.wikipedia.org/wiki/Fatal_system_error of useful low-level information about the system that can be used to debug the root cause of the problem. If the user has enabled it, the system will also write an entry to the system event log. The log entry contains information about the bug check (including the bug check code and its parameters) as well as a link which will report the bug and provide the user with prescriptive suggestions if the cause of the check is definitive and well-known. Next, if a kernel debugger is connected and active when the bug check occurs, the system will break into the debugger where the cause of the crash can be investigated. If no debugger is attached, then a blue text screen is displayed that contains information about why the error occurred, which is commonly known as a blue screen or bug check screen. The user will only see the blue screen if the system is not configured to Automatically Restart (which became the default setting in Windows XP SP2). Otherwise, it appears as though the system simply reb
