Same issue here, different hardware though. I upgraded to the latest snapshot hoping it would help, but after 2 days had another random restart.
Going to roll back to 2.1.5 for now.
I've used the report crash option every time it crashes, I don't know where that goes exactly though. I also don't have that kernel dump to paste here because it's already sent and deleted.
Here is my boot log if that helps:
