Currently, the area to preserve boot memory is reserved at the top of RAM. This leaves fadump vulnerable to memory hot-remove operations. As memory for fadump has to be reserved early in the boot process, fadump can't be registered after a memory hot-remove operation. Though this problem can't be eleminated completely, the impact can be minimized by reserving memory at an offset closer to bottom of the RAM. The offset for fadump memory reservation can be any value greater than fadump boot memory size.

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.
