drm.debug=0xff on 4770
drm-intel-nightly: 2016y-04m-18d-17h-17m-00s
The freeze is instantaneous / complete, no trace or otherwise makes it to disk
or just netconsole (hence the helpful title). Attached are the last 3000 or so
lines from netconsole with drm.debug=0xff.
Been seeing these when trying drm-intel-nightly on my 4770 (1440p+1080p HDMI)
and 4200U (1080p eDP) since about one or two weeks ago.
I have (obviously) no idea what is causing it, seems it even appears during
idling, however running a bunch of glxgears and then starting mpv with a h.264
(8-bit, 1080p, via vaapi&opengl) seems to instantly evoke it more often than
not (with compton as compositor, which uses opengl-swc for vsync).</pre>
