--- Comment #77 from dwagner <jb5sgc1n.nya at 20mm.eu> ---
Since another month has passed: I can still reproduce the crash with today's
git head of amd-staging-drm-next (and an up-to-date Arch Linux) within minutes
by replaying a video at 3 fps.

Additional new bonus bugs this time:
- system consistently hangs at soft-reboots if X11 was started before
- system crashes immediately upon X11 start if vm_update_mode=3 is used
- system crashes if the HDMI-connected TV is shut off while screen blanking

Again, the bonus bugs are either irrelevant in comparison to the instability
this report is about or have been reported already by others.
