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 , 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.
