[ Upstream commit 8195a655e5ce09550aff81b2573d9b015d520cb9 ] On this system EC interrupt triggers constantly kicking devices out of low power states and thus blocking power management. The system also has a PCIe root port hosting Alpine Ridge Thunderbolt controller and it never gets a chance to go to D3cold because of this. Since the power button works the same regardless if EC interrupt is enabled or not during s2idle, add a quirk for this machine that sets ec_no_wakeup=true preventing spurious wakeups.

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.
