That kernel is missing a bug fix from circa v3.17 to force mmip flips on IVB RCS. commit 2a92d5bca1999b69c78f3c3e97b5484985b094b9 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 8 10:40:29 2014 +0100 drm/i915: Disable RCS flips on Ivybridge We currently see random GPU hangs when using RCS flips with multiple pipes on Ivybridge. Now that we have mmio flips, we can fairly cheaply fallback to using CPU driven flips instead.

Created attachment 117622 [details] /sys/class/drm/card0/error [77438.410133] [drm] stuck on render ring [77438.410139] [drm] GPU crash dump saved to /sys/class/drm/card0/error [77438.410140] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [77438.410141] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [77438.410142] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [77438.410143] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. This happened shortly after watching a youtube video in firefox. Pithos is running in VMware Unity mode w/Lubuntu 14.04.3 (updates installed). This has happened infrequently in the past (a couple of times a month). Now, it's (about) every other day. Hardware is System 76 Gazelle p8 / Ubuntu 14.04.3. All updates installed.
