<pre><a href="mailto:n780@tuta.io">n780@tuta.io</a>, consider to attach gpu error dump rather than putting it in
comment / description body.
There are constant improvements pushed in kernel and Mesa that will benefit to
your system, so please re-test with latest kernel & Mesa (12 or 13) and mark as
REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log)
and RESOLVED/* if you cannot reproduce.
In parallel, assigning to Mesa product.
Kernel: 4.9.0-rc8+
Platform: SKL (pci id: 0x1916, pci revision: 0x07, pci subsystem: 1028:0704)
Mesa: [Please confirm your mesa version]
