In shutdown/reboot paths, the timer is not stopped:
qla2x00_shutdown
pci_device_shutdown
device_shutdown
kernel_restart_prepare
kernel_restart
sys_reboot
This causes lockups (on powerpc) when firmware config space access calls
are interrupted by smp_send_stop later in reboot.
Fixes: e30d175648 ("[SCSI] qla2xxx: Addition of shutdown callback handler.")

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.
