Created attachment 96889 [details] xz of /sys/class/drm/card0/error By filing this bug, I follow the instructions below: [26922.904349] [drm] stuck on render ring [26922.904350] [drm] stuck on blitter ring [26922.904351] [drm] GPU crash dump saved to /sys/class/drm/card0/error [26922.904352] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [26922.904352] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [26922.904352] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [26922.904352] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. I was running a program of myself that uses vtk-5.10.1 to visualize data. I am running a Gentoo linux on a Thinkpad X220 with sys-kernel/gentoo-sources-3.13.7 x11-drivers/xf86-video-intel-2.99.910 media-libs/mesa-10.1.0 x11-libs/libdrm-2.4.52 x11-base/xorg-server-1.15.0 installed. I observed these hangs over different kernel versions and versions of xf86-video-intel.
