[   47.676178] [drm] GPU HANG: ecode 7:0:0x00000000, in kwin_x11 [1519], reason: Ring hung, action: reset
[   47.676180] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[   47.676180] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[   47.676181] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[   47.676182] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

The submitted batch is full of 0xffffffff
Comment 5 Chris Wilson 2015-04-24 11:40:26 UTC 
And there's a small Y-tiled buffer just before the batch that is being written to.
Comment 6 Rohan Dhruva 2015-04-24 16:12:20 UTC 
Mika, Chris: can I do something to remediate it?
Comment 7 yann 2017-02-24 08:16:14 UTC 
We seem to have neglected the bug a bit, apologies.

ohan Dhruva, since There were improvements pushed in kernel, xf86-video-intel & mesa that will benefit to your system, so please re-test with latest kernel, xf86-video-intel & mesa and mark as REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log) and RESOLVED/* if you cannot reproduce.
Comment 8 Rohan Dhruva 2017-02-24 23:43:59 UTC 
Can't reproduce any more.
