--- Comment #2 from Todd <freedesktop at harrisonconsoles.com> ---
This is a repeatable crash using one of our existing software apps. This
application runs as-is on other hardware.

Linux ikisNuc 4.3.0-1-686-pae #1 SMP Debian 4.3.3-5 (2016-01-04) i686 GNU/Linux

motherboard is an Intel NUC DE3815TYBE

OS is Debian Stretch
All versions are equal or greater than the most recent Stack release from Jan
04, 2016.


Here is a backtrace from the application that hangs the GPU

line 458 of CGLView_CueMeter.cpp is a call to glPopMatrix()

That is the last call inside our application before the crash (frame #14)
