The QCA Rome USB Bluetooth controller has several issues once LPM gets enabled: - Fails to get enumerated in coldboot. [1] - Drains more power (~ 0.2W) when the system is in S5. [2] - Disappears after a warmboot. [2] The issue happens because the device lingers at LPM L1 in S5, so device can't get enumerated even after a reboot. Disable LPM at shutdown to solve the issue.

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.
