error.log

Hello,

Apparently Adobe's Flash Player is still not yet ready for Modern OSes, as it
led to this "crash":

--- From Xorg.0.log:
[1344934.804] (EE) intel(0): Detected a hung GPU, disabling acceleration.
[1344934.986] (EE) intel(0): When reporting this, please include
i915_error_state from debugfs and the full dmesg.

--- From dmesg (filtered only firewall stuff)
[9934868.808046] [drm] stuck on render ring
[9934868.809017] [drm] GPU HANG: ecode 0:0x9f47f9fd, in chromium [15996],
reason: Ring hung, action: reset
[9934868.809020] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[9934868.809021] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[9934868.809023] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[9934868.809024] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[9934868.809026] [drm] GPU crash dump saved to /sys/class/drm/card0/error

Attaching the /sys/class/drm/card0/error file, as suggested by the log.

Please note that I am not running the latest version of Xorg/driver/kernel:
