Both patches individually fix the symptom (lock up during reboot), but only the first one fixes the root cause. Patches are against next-20150618. The discussion thread where the problem was originally reported is "PM / Domains: Infinite loop during reboot" (http://permalink.gmane.org/gmane.linux.ports.sh.devel/45249). Thanks!
