It looks like in 4.8-rc we made a change that caused the "high" trip
point to
be acted on.
This high trip point we don't expose in thermal subsystem (the thermal
zone dump didn't show this anywhere as a trip). This is exposed by
core-dts driver only. This is the point BIOS is supposed to act, I
guess that's why you are seeing 50% clock modulation.

Are you running thermald

What is?
# ps -e | grep thermald

The output is blank. I am not running thermald.
