Have you been trying the latest nightly on its own, or along with GApps?IDK, I undo all recent device/kernel/vendor change and built with latest cm13 code, it's still crashy.
Unfortunately, I'm not able to get any useful log.

I tried I've tried the 20160523 nightly with a GApps package (arm/6.0/stock) from OpenGApps, it hard reset twice before I could even use the setup wizard.
Then tried again without flashing any google apps, and so far (30~ mins - 2 phone calls and some texts) I've yet to have an issue, but I'm missing having the play store and everything.
Starting to think the issue might be from the GApps flash, so I'm going to see if it unpacks anything extra along with the apps that could be causing the issues.
