Every now and than my desktop freezes for a couple of minutes. I can move the mouse pointer but it gets stuck in a single display (I have two).

Hi Christopher,

Sometime ago, after I reported this bug, I had already updated my BIOS to 2.98:

~ $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
K01 v02.98
03/18/2015

Since then I've got less video issues, but I cannot tell if they were fixed by the BIOS update or by some other update like the new kernel I have now (3.19).

Those 1-2 minutes freezes definitely have stopped or at least they are not so frequent. But sometimes my Unity still freezes for a few seconds like the first time when I press the Super key to bring up the Dash Home screen or when I run apt-get install and it starts configuring some package. I don't know if they are related. And also I am still seeing i915 crashes and errors in dmesg:

[penalvch (penalvch)]

CB, given you are experiencing a kernel crash in a graphics driver, this would be the cause of your displays freezes.

Hence, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

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, Y, and Z are numbers corresponding to the kernel version.

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.

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

Thank you for your understanding.

[penalvch (penalvch)]

CB, did this problem not occur in a kernel series prior to 3.16?

[CB (cbrchrt)]

If my memory doesn't fail me, it occurred since when I've got this machine and it had Ubuntu 14.04 or 14.04.1.

[penalvch (penalvch)]

CB, the issue you are reporting is an upstream one. Could you please report this problem following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/kernel ?

Thank you for your understanding.

[CB (cbrchrt)]

Hi Christopher, the steps are a little confusing for me. I've prepared the report according to the instructions from Ubuntu's Wiki, but looking at Intel's instructions it looks like they need other information. I will have to build and and redo the test using their nightly release. Is that so? In case yes, I will need a few to more days to be able to test it properly.

[penalvch (penalvch)]

CB, binaries of intel-drm-nightly are already available via the mainline kernel support article, so you don't need to build anything:

CB, if one wants to provide current results, one would test the latest mainline kernel 4.4-rc5 (not 4.3.x), and if still reproducible there drm-intel-nightly.

It looks like it was finally fixed on 4.7.0-040700-generic. I've just upgraded and for the first time there aren't any call traces in my dmesg.
