--- Comment #8 from Josep Torra <n770galaxy at gmail.com> ---
It's most often reproduced in the Dell T5600 systems with "Intel Corporation
C600/X79 series chipset" and FirePro W9000.

But we also reproduced it few other systems based on chipset "Intel Corporation
C610/X99 series chipset" and FirePro W600.

Not reproducible so far with an Intel Skylake system, Asus Z170 Pro gaming
motherboard, with FirePro W600.

In the Dell T5600 the issue becomes hidden with the drm debug enabled in the
following way.

echo 0xf > /sys/module/drm/parameters/debug

It's still triggered with 0xe instead of 0xf.
