For the crash here, I did: suspend to RAM, plug power back in, wake up. Laptop crashed about 3 seconds after wakeup. I'm on vacation with no hardware to get a proper crash dump or even serial console, but I have a bad screenshot. Boy do I wish this could be saved in some kind of NVRAM instead like on android.
