Analysis & Root Cause
===================
Comment 1 Jani Nikula 2017-01-20 08:26:55 UTC 
What makes you think this is an Intel graphics bug?
Comment 2 yann 2017-01-20 16:04:20 UTC 
moreover, can you attach kernel log top confirm it is graphics related issue?
Comment 3 Ricardo 2017-02-24 15:30:30 UTC 
Hi please review prior comments and important to add logs, once you provided the necessary information please move the bug to REOPEN state
Comment 4 Glody Guo 2017-02-28 06:36:25 UTC 
This error occurs on latest kernel(4.10.0-rc1-11391-g81f56e3), On ChromeOS defualt kernel(v3.18 for SKL), this issue unable to reproduce. So we assume it's kernel related issue.

Again there is no logs attach. here is information for you to help you

At the same time you can also use latest https://cgit.freedesktop.org/drm-tip to test

Once the information is provided again move the status to Reopen (I'm moving it to NEEDINFO)
