thermal_zone_device_check --> thermal_zone_device_update --> handle_thermal_trip --> handle_critical_trips --> orderly_poweroff The above sequence happens every 250/500 mS based on the configuration. The orderly_poweroff function is getting called every 250/500 mS. With a full fledged file system it takes at least 5-10 Seconds to power off gracefully. In that period due to the thermal_zone_device_check triggering periodically the thermal work queues bombard with orderly_poweroff calls multiple times eventually leading to failures in gracefully powering off the system. Make sure that orderly_poweroff is called only once. Signed-off-by: Keerthy <j-keerthy@ti.com> Acked-by: Eduardo Valentin <edubezval@gmail.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
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.
