Comment # 186
on bug 91880
from Chris Heald
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: kernel: [ 116.904013] radeon 0000:06:00.0: GPU
