Claire was able to retest with the 4.8.0-31.33~16.04.1 Yakkety HWE kernel. She says the problem is still happening (ie. screen crashes and goes blank after about 20min). She captured her dmesg output after reproducing the issue with 4.8.0-31.33~16.04.1. I have attached it here, but am not seeing anything obvious, but would be good to get some second opinions. Thanks.
