gpu crash dump

Every now and then, this happens:

    [ 8580.301788] [drm] stuck on render ring
    [ 8580.302334] [drm] GPU HANG: ecode 0:0xf5fffffe, in chromium [695], reason: Ring hung, action: reset
    [ 8580.302336] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
    [ 8580.302336] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
    [ 8580.302337] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
    [ 8580.302338] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
    [ 8580.302339] [drm] GPU crash dump saved to /sys/class/drm/card0/error
    [ 8582.303190] [drm] Enabling RC6 states: RC6 on, RC6p on, RC6pp off
