An additional note. Based on a bug that I have been supplying information to https://bugs.freedesktop.org/show_bug.cgi?id=75394 because initially there would be an error noted in my syslog "[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle". This error has since stopped being entered into my syslog. The reason that I'm running a non-Ubuntu kernel but instead the most current stable drm-intel kernel from here http://kernel.ubuntu.com /~kernel-ppa/mainline/drm-intel-next/ is that I posted a message about this issue in the Intel-GFX mailing list and was contacted by Chris Wilson, Intel Open Source Technology Centre who had me update to kernel 4.0.0-997-generic. I also updated the driver per his instructions which can be seen in the attached Xorg.0.log. I have also filed a bug report about this previously - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1402331 A bug report that I personally filed at freedesktop.org - https://bugs.freedesktop.org/show_bug.cgi?id=91495 can also be referenced for more information. When the freeze happens I'm able to SSH into the desktop from my tablet. I've run some GDB back traces on Gnome- Shell. The one from a freeze in August is attached. The latest freeze was on 10 Sept at 5:03am after a runtime of 16d9h12m. The system was fairly idle at this time as there were no applications running using video such as Firefox or Evolution just background apps.
