Affects		Status	Importance	Assigned to	Milestone
	linux (Ubuntu)	Expired	Medium	Unassigned

Bug Description

randomly system will freeze. Freeze in that screen will be blank and system will not accept keyboard commands to change to a terminal or to chagne the caps lock light.

Can ssh into the laptop while its "frozen". The syslog/journal shows a kenel stacktrace (below)

Seems more common after suspending.

don't recall it happening with 15.04. If it did start with 15.04 it would of been with the latter kernels.

Seems similar to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1454868

Many thanks for your help. much appreciated.

I have updated the bios to v506 (04/15/2015 MDY) today.

It is an intermittent bug, so I'll report back after two weeks.
( If it works fine for two weeks then I expect it is fixed.)

Time: Yesterday morning

symptoms:
found laptop frozen with black screen, was working the night before and was left on.
Using a Ubuntu mainline 4.4.x kernel.

Unable to ping or connect to over the network, where with the above bug I was able to.

Actions:
Have removed the 4.4.x kernels, now using standard 4.2 Wily kernel.
Will report back

using std wily kernel "4.2.0-25-generic" my system will freeze over night.
Happened 2 nights in a row. Leave the laptop plugged in and turned on, in the morning system is unresponsive. capslock light doesn't change.
Cannot be pinged or ssh'ed into across network (wifi)
When booting usual spach screen doesn't appear. Need to gues it's at encryption dialog entry, and type passwords to boot.
so have removed "quiet splash" boot options.

Initial bug report above was done while ssh'ed in, as keyboard not working, screen blank.
Seemed like a video card driver issue as i was unable to get the screen to appear after attempting to restart lightdm service.

have installed and have been running "4.4.0-997-generic" from ubuntu mainline intel driver kernel. (linux-image-4.4.0-997-generic_4.4.0-997.201601242100_amd64.deb)
(after 4.2 kernel)
Has been stable and wakes from suspend mode happily.

Will continue to report back if chagnes in behaviour.

using standard 4.2 Wily kernel, system will freeze commonly while unlocking. (unsing gnome & lightdm)

Have switched to a older kernel which has been very stable so far. no errors.
Will report back.

I am having similar problems with xenial (Kernel 4.4). Xorg crash, console is "frozen". Machine is up and running (can log in via ssh).

Shutdown/reboot does not work. Machine must be powercycled to be usable again.

Seems to occur after screen has been idle for sometime.

My workaround is to use kernel 3.14.1-031401-generic.

Being that I was able to ssh in when the UI froze suggested to me it was a xorg related bug connected to the kernel.
Kernel as old kernels worked (as above)
So Kernel video drivers ?

Assume its an issue with the Intel drivers.

When ssh'ed in I was unable to get the lightdm service to restart.

Using the above kernel my laptop has been up for 13 days when before it would usually freeze after waking from suspend or after screen turns off. Odd thing was that the keyboard wou;dn't allow switching to a virtual terminal.
Didn't try sysreq keys.

Daniel Walton, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.
