I read the link Zanna provided in comments but there is something else you should look at: Bay Trail Freezing. There are over 500 messages here from Bay Trail users (plus a few other Intel CPUs).

The messages start in December 2015 so scroll down 3rd from the end (as of October 24, 2016) and you will see this post:

One week so far no crashes.  4.8.0-rc8-amd64



In rc.local this script is run at boot...


echo 1 > /sys/devices/system/cpu/cpu0/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo


I’ve read hundreds of these posts and some users can report β€œsuccess” one day and the report back with β€œfailed again!” a few days later. Above the author recommends Kernel version 4.8.0-rc8 but I would recommend using stable kernel version 4.8.4 instead. A summary for doing this is:

cd /tmp
sudo dpkg -i *.deb
sudo reboot

Note: Version 4.8.4 is the most current stable kernel as of October 24, 2016.

October 30, 2016 update

From today’s bug mail the following solution was proposed:

thorsten: Try the commands below, and report back. These eliminate hang ups on
my N2930 with kernel 4.7 (Gentoo).

First start kernel with: intel_idle.max_cstate=0

Then give these commands as root:

echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo
echo 1 > /sys/devices/system/cpu/cpu0/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/cpu1/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/cpu2/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/cpu3/cpuidle/state3/disable
