--- Comment #186 from Chris Heald <cheald at gmail.com> ---
I've been doing a lot of experimentation, and I've found a few more things that
I feel are probably related:
* I can force a system hard-lock by doing anything which disables a monitor.
Notably, going full-screen under KDE/Xorg does this, but I can trigger it just
as easily by disabling a monitor with xrandr. Fullscreen under gnome doesn't
seem to trigger the issue, which I suspect is due to gnome's using mutter for
screen management.
* Occassioanlly, the system boots up and gets stuck with a 150MHz memory clock,
rather than clocking up to the 1500MHz state. This causes the display
corruption even if the sclk is set to 500MHz+. Setting the mclk mask manually
fixes display corruption.
* I've been experimenting with different kernels ranging from 4.4 to 4.16rc5.
Earlier kernels feel more susceptible to hard-locking, though the later kernels
aren't immune to it.
* I tried a fresh Ubuntu 16.04 LTS install, and while it did NOT exhibit the
artifacting behavior, the system hard-locked within a few minutes of light
desktop usage.
I've had a few classes of exceptions show up in kern.log:
On 4.4, my kde/wayland session hard-froze when moving a window, and produced a
log like this:

Possibly related, if I `cat pp_num_states` from a terminal, I get a
segmentation fault:
root at Gaia:~# cat /sys/class/drm/card0/device/pp_num_states
Segmentation fault
I'm going to continue to dig. Let me know what logs/tests/whatnot I can provide
that would be useful.
