 This is just before the crash.  The EC is sending a 1% battery tick event.
 In the rest of your log no events are sent at wakeup time.

 I've duplicated your crash on a C2 sku 298 [1].  Rather than charging I
 was swapping in and out a full battery thus generating EC events.  I'm
 thinking this hang is related to the EC sending events rather than with
 the battery charging.

 [1] A C2 is a C1 with the 1.8V SD power switch modification.
