At least on one Dell system the PNP motherboard resources device includes resources used by WDAT table. Since PNP gets initialized before WDAT it results following error and no watchdog: platform wdat_wdt: failed to claim resource 3: [io 0x046a-0x046c] ACPI: watchdog: Device creation failed: -16 Now, the PNP system driver is already accustomed with the situation that it cannot reserve all those motherboard resources because drivers using those might have reserved them already. In addition putting WDAT table resources under motherboard resources device makes sense in general. Fix this by initializing WDAT right before PNP. This allows WDAT to reserve all its resources and still keeps PNP system driver happy.

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.
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.
