Okay, I did one-by-one reverts, and the one above, i.e.

	commit 021182e52fe01c1f7b126f97fd6ba048dc4234fd
	Author: Thomas Garnier <thgarnie@google.com>
	Date:   Tue Jun 21 17:47:03 2016 -0700

	    x86/mm: Enable KASLR for physical mapping memory regions

is the one that is the culprit on my machine. With this one reverted, 
resume hibernation doesn't reboot (tripple fault?), but proceeds 
succesfully.
