serial terminal capture (power on, login, shutdown)
Hi,
this bug is similar to <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [radeon] kernel hangs during shutdown - drm-next-4.9-/+wip"
href="show_bug.cgi?id=98200">Bug 98200</a>.
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.</pre>
