Since the drivers such as HPRE/SEC/ZIP do not implement 'pci_driver.shutdow', a RAS will be triggered at OS rebooting or shutting down as the hardware device is processing request. The log looks like this: NOTICE: [NimbusSecNodeType1]:[2372L]This is sec, Base = 0x141800000 NOTICE: [NimbusSecHandle]:[2319L] SecIntSt = 0x3 NOTICE: [NimbusSecHandle]:[2320L] SecQmIntStatus = 0x2 NOTICE: [PrintSecurityType]:[344L] SecurityType is RECOVERABLE! This patch offers a new API in qm to shutdown devices, and add shutdown callbacks in ACC driver based on this new API. So the running devices will be stopped when the OS reboot or shutdown.

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.
