NMIs received during the crash path are problematic as hpwdt_pretimeout handling of the NMI would cause a reentry into kdump. The situation is complicated in that I/O errors can be signaled as NMI circumventing hpwdt_pretimeout's attempt to not claim NMI not associated with either the WDT or the iLO NMI switch. These NMI can additionally cause a secondary NMI which cause the system to hang. By disabling pretimeout and hpwdtimeout in crash path we both reduce the risk of receiving an NMI and simuletaneously leave the WDT running (if it was already in use) to allow the WDT to break the system out of hangs by the WDT reset.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
