<pre>Hello Wanglei, is system hangup occasional or 100% reproducible?
Your kernel version is quite old. Please try to reproduce the failure with the
latest kernel (canonical/kernel.org longterm 4.4.70 or preferable with drm-tip
or stable 4.11.3) and provide the logs from that as instructed in
<a href="https://01.org/linuxgraphics/documentation/how-report-bugs">https://01.org/linuxgraphics/documentation/how-report-bugs</a>.
It might also help if you can attach i915_display_info file from
/sys/kernel/debug/dri/0 (if you can generate image from drm-tip with debugfs
enabled).</pre>
