commit 7ea6ec4c25294e8bc8788148ef854df92ee8dc5e upstream. If the system has no mirrored memory or uses crashkernel.high while kernelcore=mirror is enabled on the command line then during crashkernel, there will be limited mirrored memory and this usually leads to OOM. To solve this problem, disable the mirror feature during crashkernel.

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.
