We will collect the ramdump of BT controller when hardware error event received before rebooting the HCI layer. Before restarting a subsystem or a process running on a subsystem, it is often required to request either a subsystem or a process to perform proper cache dump and software failure reason into a memory buffer which application processor can retrieve afterwards. SW developers can often provide initial investigation by looking into that debugging information.

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.
