It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continuing the operation may risk escalating system instability, and a system reboot is easier than attempted recovery.
Most computers have a reset line that brings the device into the startup state and is active for a short time after powering on. For example, in the x86 architecture, asserting the RESET line halts the CPU; this is done after the system is switched on and before the power supply has asserted "power good" to indicate that it is ready to supply ...
This is in contrast to the Windows NT version of BSoDs, which prevented the user from using the computer until it has been powered off or restarted (usually automatic for the latter). The most common BSoD is displayed on an 80×25 text-mode screen, which is the operating system's way of reporting an interrupt caused by a processor exception; it ...
Modern boot loaders make use of concurrency, meaning they can run multiple processor cores, and threads at the same time, which add extra layers of complexity to secure booting. Matthew Garrett argued that booting security serves a legitimate goal but in doing so chooses defaults that are hostile to users. [76]
Restart your computer: If you haven't shut down your computer in a while, we recommend that you begin troubleshooting by restarting your computer. This will help to clear the internal memory of your computer (RAM) and will often resolve many issues. Use a different browser:

At the time of the incident, CrowdStrike said it had more than 24,000 customers, [42] including nearly 60% of Fortune 500 companies and more than half of the Fortune 1000. [ 43 ] [ 44 ] On 20 July, Microsoft estimated that 8.5 million devices were affected by the update, which it said was less than one percent of all Windows devices.
This delay allows time for the computer to boot before the watchdog is enabled. Without this delay, the watchdog would timeout and invoke a subsequent reset before the computer can run its application software — the software which kicks the watchdog — and the system would become stuck in an endless cycle of incomplete reboots.
