[drm] GPU HANG: ecode 3:0:0x0071e0c0, in Xorg [2106], reason: Ring hung, action: reset
Comment 1 Chris Wilson 2015-04-27 20:22:37 UTC 
The crash occurs on the instruction to set a colour buffer (with Y-tiling) that is currently being fenced with X.  It is used earlier in the batch as a Y-tiled texture. The hang could be at the pipeline stall at the end of that sampling - hard to say for sure. At any rate, that we have a dirty fence register seems to be the most likely explanation.
