I am having an issue with the suspend to disk feature for ARM Linux Kernel version:

Linux 4.2.0-rc3-00115-gc5dfd65-dirty #4 SMP PREEMPT Fri Jul 24 12:15:54 CEST 2015 armv7l GNU/Linux

I can suspend to disk fine, however when resuming it hangs at disabling non-boot CPUs and does a reboot after about 10 seconds.

Excerpt from Serial Console when I do "echo disk > /sys/power/state":

PM: writing image.
PM: Using 1 thread(s) for compression.

Excerpt from the Serial Console when I do a coldstart:

Any assistance will be greatly appreciated.
