Shortly after trading a tablet for a Toshiba Satellite Click 2 (Hybrid touchscreen laptop) I installed Linux. I soon found out that there is a bug in the kernel that results in Linux intermittently crashing on BayTrail integrated graphics devices. So to make sure it wasnt an installation problem I tried out different Ubuntu desktop environments distros and other Linux distros like Manjaro. Same problem. I installed Android x86 and the same problem occurs. It will be running fine and then it shuts off without any warning as if the battery were yanked from the device or the power plug was pulled. Dead. I then have to boot it back up. I installed Windows 10 and it doesnt crash so it is for sure that bug. I googled and found the "intel_idle.max_cstate=1" kernel boot flag. As well as the boot flag "intel_pstate=disable".

I applied these boot flags both from the GRUB menu at boot and then in the /etc/default/grub file. I still get random crashes. They are not isolated to any action or application either. Any way to fix this?

Any help is appreciated thanks!

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

Options


GRUB_CMDLINE_LINUX_DEFAULT=intel_idle.max_cstate=5


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




#!/bin/bash
echo 1 > /sys/devices/system/cpu/cpu0/cpuidle/state3/disable
echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo


thanks

I've read hundreds of these posts and some users can report "success" one day and the report back with "failed 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
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.4/linux-headers-4.8.4-040804_4.8.4-040804.201610220733_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.4/linux-headers-4.8.4-040804-generic_4.8.4-040804.201610220733_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.4/linux-image-4.8.4-040804-generic_4.8.4-040804.201610220733_amd64.deb
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
