The intent of this parameter is unclear and it sets up a race between the reset of the system by ASR and crashdump. The length of time between receipt of the pretimeout NMI and the ASR reset of the system is fixed by hardware. Turning the parameter off doesn't necessairly prevent a crash dump. Also, having the ASR reset occur while the system is crash dumping doesn't imply that the dump was hung given the short duration between the NMI and the reset. This parameter is not a substitute for having a architected watchdog crashdump hang detection paridigm.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
