Running Ubuntu 14.04 on my old Macbook, I get the following error on every boot. It doesn't seem to cause issues, but always happens.
[ 18.644792] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 18.644796] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 18.644797] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 18.644799] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 18.644801] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

This seems like an old issue that was resolved, but is back in 14.04? I have found similar, older bug reports, but none against 14.04.
