Hi. I am getting something similar and I think it may be reproducible. Since I
upgraded to kernel 4 and also upgraded to:
libdrm-git (2.4.60.17.g8dff7a0-1)
xf86-video-ati-git (7.5.0.r34.g6291baa-1
mesa-dri-git 10.6.0_devel.68990-1  (i don't know what commit, but it's from 1-2
days ago, currently recompiling with latest commit to retry)
mesa-git 10.6.0_devel.68990-1
mesa-libgl-git 10.6.0_devel.68990-1
mesa-vaapi-git 10.6.0_devel.68990-1
mesa-vdpau-git 10.6.0_devel.68990-1
opencl-mesa-git 10.6.0_devel.68990-1


I got one random screen freeze(no blanking though) and system was locked up
while viewing a youtube video in chromium and using the volume buttons.
(nothing in the logs, probably because the system froze)

And this one which is probably reproducible, the next day, I plugged in my
webcam, and as soon as vlc was attempting to display it (even though it looked
like a black picture)  screen froze, then blacked the screen (can't remember if
with backlight or not) and then I unplugged the webcam before I
shutdown(pressed power button once after Ctrl+Alt+F2 to switch to a non-gfx
virtual terminal console) and thus see the log on next boot(journalctl -b -1)

Mar 23 15:06:15 manji kernel: radeon 0000:00:01.0: ring 0 stalled for more than
10483msec
Mar 23 15:06:15 manji kernel: radeon 0000:00:01.0: GPU lockup (current fence id
0x0000000000012c15 last fence 
id 0x0000000000012cdc on ring 0)

(full log included in attachment)
the above messages are the beginning of when it got blank

I don't know if this is a new issue because I haven't tried my webcam for at
least 1-2 months before this. But I've only recently(1-2days) upgraded to
kernel 4, from 3.19.

apparently after updating mesa(to try next) the new version is
10.6.0_devel.67962-1 but the old one(with the above error) was
10.6.0_devel.68990-1
using manjaro linux.
