GPU crash dump from /sys/class/drm/card0/error

GPU hang on i5-2400S (Sandybridge, "Intel HD graphics 2000")

Running current google chrome stable on up-to-date Fedora 20 and very recent
self-built kernel, i915 seems to hang particularly when running flash
applications:

  [drm] stuck on render ring
  [drm] stuck on blitter ring
  [drm] GPU HANG: ecode 0:0xf4e9fffe, in Xorg [854], reason: Ring hung, action:
reset
  [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
  [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
  [drm] drm/i915 developers can then reassign to the right component if it's
not a kernel issue.
  [drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
  [drm] GPU crash dump saved to /sys/class/drm/card0/error
