Created attachment 113706 [details] 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.

Please note that I am not running the latest version of Xorg/driver/kernel: X.Org X Server 1.16.1 (Debian: 1:7.7+7) Kernel 3.16-3-amd64 #1 SMP Debian 3.16.5-1 (Debian: 3.16.5-1) Driver: ?

Hello, Having a quick look at the kernel's sources, it seems that at least the ENODEV code for the chip reset should be fixed in the "mainline" branch (3.19), but not before (3.18.7). Regards, Christophe.
I suspect this may be another duplicate of the bug 80568, fixed (worked-around) by this commit: commit c4fd0c9052dd391d6f2e9bb8e6da209dfc7ef35b Author: Kenneth Graunke <kenneth@whitecape.org> Date: Sat Jan 17 23:21:15 2015 -0800 i965: Work around mysterious Gen4 GPU hangs with minimal state changes. Gen4 hardware appears to GPU hang frequently when using Chromium, and also when running 'glmark2 -b ideas'. Most of the error states contain 3DPRIMITIVE commands in quick succession, with very few state packets between them - usually VERTEX_BUFFERS/ELEMENTS and CONSTANT_BUFFER. I trimmed an apitrace of the glmark2 hang down to two draw calls with a glUniformMatrix4fv call between the two. Either draw by itself works fine, but together, they hang the GPU. Removing the glUniform call makes the hangs disappear. In the hardware state, this translates to removing the CONSTANT_BUFFER packet between the two 3DPRIMITIVE packets. Flushing before emitting CONSTANT_BUFFER packets also appears to make the hangs disappear. I observed a slowdown in glxgears by doing it all the time, so I've chosen to only do it when BRW_NEW_BATCH and BRW_NEW_PSP are unset (i.e. we haven't done a CS_URB_STATE change or already flushed the whole pipeline). I'd much rather understand the problem, but at this point, I don't see how we'd ever be able to track it down further. We have no real tools, and the hardware people moved on years ago. I've analyzed 20+ error states and read every scrap of documentation I could find.
