Wolfram reports that his R-Car H2-based Lager board can no longer be
rebooted in v5.11-rc1, as it crashes with an imprecise external abort.
The issue can be reproduced on other boards (e.g. Koelsch with R-Car
M2-W) too, if CONFIG_IP_PNP is disabled, and the Ethernet interface is
down at reboot time:

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.
