<pre>We seem to have neglected the bug a bit, apologies.
There were improvements pushed in kernel and Mesa that will benefit to your
system, so please re-test with latest kernel & Mesa to see if this issue is
still occurring.
(you may also collect and attach logs collected thanks to apitrace:
<a href="http://apitrace.github.io/">http://apitrace.github.io/</a>)
In parallel, assigning to Mesa product (please let me know if I am mistaken
with this GPU Hang).
Kernel: 3.13.0-62-generic
Platform: Broadwell-U (pci id: 0x1616)
Mesa: [Please confirm your mesa version]
