Hi,
this bug is similar to Bug 98200.
Since upgrade from kernel 4.8.17 to 4.9.{1,2,5} I am unable to restart or shutdown my PC. Poweroff/restart always ends with black screen (display shows "no signal"). System stays frozen with fans / hard discs spinning. Reset button does not bring the system back - it stays completely frozen. Only manual (power button) power off/on cycle brings the system back.
GPU: [AMD/ATI] Juniper XT [Radeon HD 5770]
I was able to capture kernel messages over serial line, last lines:
... [ 136.326236] systemd-shutdown[1]: All loop devices detached. [ 136.353887] kvm: exiting hardware virtualization [ 136.380090] Console: switching to colour VGA+ 80x25 [ 136.406675] [drm] radeon: finishing device.
I tested kernel 4.9.1, 4.9.2 and 4.9.5.
