<pre>I see the following error in dmesg:
[14523.006746] [drm] stuck on render ring
[14523.008567] [drm] GPU HANG: ecode 0:0x0fdf00ac, in Xorg.bin [1505], reason:
Ring hung, action: reset
[14523.008577] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[14523.008582] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[14523.008587] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[14523.008592] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[14523.008597] [drm] GPU crash dump saved to /sys/class/drm/card0/error
I have the error file saved, but it is big and therefore I did not add it here.
I can certainly make it available though.
System behavoir:
- sometimes upon resume from suspend to RAM: it takes about 5 seconds longer to
wake up, but no more obvious problems
- trying to play a video is unsuccessful: no video rendered, sound is played,
X.org becomes unusable (very very slow reaction: switching to another window >
30 seconds), but the system is alive; switching to a console and killing the
video player process does not help, the system is still slow; only a reboot
helps; when shutting down, the screen flickers
- when logging out and sddm tries to show the logon display, screen flickers
for about 30 secs before sddm is shown; no obvious problems afterwards
Software: Fedora 21 beta (not tested with earlier versions)
Hardware:
Lenovo Yoga Pro 3
Intel Broadwell CPU
No additional GPU other than the Broadwell included GPU
3200x1800 screen resolution</pre>
