In a "dual kernel" layout, kdump uses kexec to boot another kernel and obtain a memory dump. [3]: 10 In the event of a kernel crash, kdump preserves system consistency by booting another Linux kernel, which is known as the dump-capture kernel, and using it to export and save a memory dump.
The resulting memory dump file may be debugged later, using a kernel debugger. For Windows, WinDBG or KD debuggers from Debugging Tools for Windows are used. [ 31 ] A debugger is necessary to obtain a stack trace, and may be required to ascertain the true cause of the problem; as the information on-screen is limited and thus possibly misleading ...
When a bug check is issued, a crash dump file will be created if the system is configured to create them. [2] This file contains a "snapshot" of useful low-level information about the system that can be used to debug the root cause of the problem and possibly other things in the background.
User-mode memory dump, also known as minidump, [23] is a memory dump of a single process. It contains selected data records: full or partial (filtered) process memory; list of the threads with their call stacks and state (such as registers or TEB ); information about handles to the kernel objects; list of loaded and unloaded libraries .
Debugging information is saved in NVRAM and written to a log file on reboot. In 10.7 there is a feature to automatically restart after a kernel panic. In 10.7 there is a feature to automatically restart after a kernel panic.
Its appearance often means that the hard drive is corrupted and it will attempt to clean up, check, and/or repair the TiVo Media File System. [ 2 ] [ 3 ] A Blue Screen of Death on a Windows Insider build appears as green instead of blue, starting with build 14997.

When pure demand paging is used, pages are loaded only when they are referenced. A program from a memory mapped file begins execution with none of its pages in RAM. As the program commits page faults, the operating system copies the needed pages from a file, e.g., memory-mapped file, paging file, or a swap partition containing the page data ...
