Dear Francisco

I had my first reboot with N4 (and with FK, been there since r111). So that I've changed from Stock into Carbon less than two weeks ago, probably it's ROM related, but anyway... take a look on last_kmsg for it that could help.

Boot info:

Last boot reason: reboot

I was installing updates from play store, and that was during last update of three... that was last FKu beta. It seems to be properly updated, though.

'Last boot reason: reboot', so, I think it's not kernel derp, but you're the expert in last_kmsg.

Thanks
