Attached is the log from Pat which shows the actual problem together
with some verbose logging.

>From the log the reason for the continous hold wakelock MT662x are therm
events we're receiving from the WiFi/BT/.. combo chip. They start to
flood at one point which will keep the device awake. One krillin
interestingly we don't have support for this enabled at all and those
events just never come in. What triggers the flood of therm events isn't
clear yet but a first attempt to just disable them gave very good
results as Pat showed above.

I've uploaded a fix for this to get some more eyes on this.
