Chris Rainey, to advise, given this is Lauchpad (downstream reporting system) it's impossible to mark it a duplicate of an freedesktop.org (upstream reporting system) report, or any other reporting system. Also, this is not considered being tracked at bugzilla, as this hasn't been confirmed to be related.
Despite that, this report (downstream) is still pending https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1503731/comments/12 . Given your belief there is a commonality to an upstream report, it would help to provide evidence of it by confirming the regression commit noted in the upstream report is indeed the same for your hardware. ** Changed in: linux (Ubuntu) Importance: High => Low -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1503731 Title: 8086:0f31 Ubuntu 15.04-15.10 freezes totally Status in linux package in Ubuntu: Incomplete Bug description: Ever since I first installed 15.04 back in April/May on my new DELL Inspiron 3646 I have experienced frequent(daily/every-other- day)complete lockups(cannot even switch to console(Alt-F1,F2,etc.). I have determined that the issue is related to the 'i915' driver in relation to my GPU. I'm currently using intel-linux-graphics- installer_1.2.0-0intel1_amd64.deb from https://01.org/linuxgraphics with similar results (maybe a little better than the stock i915 stack in 15.04). WORKAROUND: Use kernel boot parameter: intel_idle.max_cstate=1 I have gained _significant_ improvements in reliability / stability by using parameters in the i915 module: /etc/modprobe.d/i915.conf: options i915 semaphores=1 and / or /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable" and / or /usr/share/X11/xorg.conf.d/20-intel.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "TearFree" "1" EndSection and / or Disable "Intel Virtualization Technologies" in the BIOS.
