Hi. Mark, could you please re-check this test? I tried it locally, output
below.  Also there are no GPU hangs at all.

den at den-HP-ZBook-14u-G4:~/repositories/piglit/bin$ ./glsl-max-varyings -auto
Vertical axis: Increasing numbers of varyings.
Horizontal axis: Which of the varyings contains the color.
GL_MAX_VARYING_FLOATS = 128
PIGLIT: {"result": "pass" }

Tested on 3 different PC's with the similar setup (all with 2 monitors,
laptop+additional):
Ubuntu 16.04
Mesa 18.3.0-git (from 03.09), Mesa 18.0.5 (release)
KBL
HSW
_______________________
Interesting, that on another distros test fails in different ways (but also
without the hang):
1. 
Ubuntu 18.04
Mesa 18.3.0-git
KBL
3 monitors connected
Test is failing on the laptop's monitor only. If you run test on connected
display - it passes.

2.
Antergos
Mesa 18.3.0-git (debug)
KBL
2 monitors connected - fails on both of them
