<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.
In parallel, assigning to Mesa product (please let me know if I am mistaken
with this GPU Hang).
Kernel: 4.1.4-1-ARCH
Platform: Braswell (pci id: 0x22b1)
Mesa: [Please confirm your mesa version]
