Does anybody else use hibernate and encounters the same crash?
A few days/weeks ago I forgot to plugin the power cable, and as a result there was a sudden suspend to disk. I was able to resume from the swap partition. So its likely hardware specific.
If you are curious, install kernel-vanilla and report it also upstream at bugzilla.kernel.org. Maybe its a regression? Install the 4.4 based kernel from Leap 42.2 to check if it works any better.

I've been hunting the S4 problem for a while (mostly for SLE12-SP2), and my finding is: this is no new problem. The first "regression" was introduced in 4.2 kernel. Since then S4 has been broken, occasionally reboots. The reboot probability increased since 4.3. Then, the S4 issue has been improved in 4.7, and again more stabilized in the recent 4.8-rc. With 4.8-rc, I didn't see this problem any longer. Funnily enough, both the regression and the fix above are irrelevant with the real culprits. Yes, it's plural: there are multiple causes leading to S4 resume problems. AFAIK, one is in arch/x86/power stuff, and another is in i915 driver. But the commits that caused the apparent regressions and fixes mentioned above were all about mm changes. They just casually triggered or cured the hidden issues by some mystic reason. In anyway, I'm going to backport the fixes to TW kernel in the next week. Let's see whether it addresses enough.
