Sorry, was traveling.

Testing with 4.10.8-200.fc25.x86_64: freezer, devices and platform are
OK, it breaks at "processors".
The screen stays off, and the machine no longer answers to ping.

(Without coretemp loaded, the machine survives all the states. There
are some graphics glitches and radeon error messages)
