--- Comment #19 from Adam Bolte <abolte@systemsaviour.com> ---
Updated to a stable Linux 4.11.0 kernel, with the LED patch that's still not
upstream (from https://bugs.freedesktop.org/show_bug.cgi?id=97590). Says
"Tainted" due to using the vhba (Virtual SCSI HBA, built via dkms) kernel
module from the CDEmu project. All config options are typical - built using
`make olddefconfig` on an up to date Debian Stretch install.

This happened while playing The Darkness II (a d3d9 game) under a patched (for
Darkness II compatibility - https://bugs.winehq.org/attachment.cgi?id=54454)
Wine 2.8. This was *not* using Gallium on Nine. The screen froze up (I couldn't
alt-tab or switch virtual desktops) so I had to SSH in from a laptop to power
off safely.

Device: AMD FIJI (DRM 3.10.0 / 4.11.0+, LLVM 4.0.1) (0x7300)
Version: 17.2.0
OpenGL renderer string: Gallium 0.4 on AMD FIJI (DRM 3.10.0 / 4.11.0+, LLVM
4.0.1)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.0-devel
(git-3db35a8bb9)
OpenGL core profile shading language version string: 4.50

Happened while running Mesa master (currently
f347bac30f4045a9583f95a5776484b1a2947183, Thu May 18 10:21:59 2017 +0300), with
the Dying Light patch set from
https://lists.freedesktop.org/archives/mesa-dev/2017-May/155428.html on top.

I only observed a crash just the one time during the entire ~6h play-through.
