[ 1759.718] (EE) intel(0): When reporting this, please include i915_error_state from debugfs and the full dmesg. I am not sure what exactly triggers this, but I can reproduce the error pretty easily under the following conditions: - external monitor switched on (connected by DisplayPort) - Laptop monitor switched off - Chrome running (Flash ads or video playing) Yesterday I was using the machine *without an external Monitor* for a few hours and this error did *not* happen even though I was using Chrome and Flash extensively. How could I find the culprit of this error? Here are some version numbers that might be interesting: Kernel: 3.8.7 Mesa: 9.1.1 xorg-server: 1.13.3 xf86-video-intel: 2.21.6

It just happened again and I got this in dmesg: Apr 16 13:29:26 dain kernel: [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung Apr 16 13:29:26 dain kernel: [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state Apr 16 13:29:26 dain kernel: [drm:kick_ring] *ERROR* Kicking stuck wait on render ring
This still happens with the following versions Mesa 9.1.4, xorg-server 1.14.2, xf86-video-intel 2.21.12, Linux 3.10.4. This is also a problem on a colleague's notebook, which is from the same line as mine (Lenovo X220). That notebook is running Ubuntu 13.04.
This seems to be related to --enable-sna in xf86-video-intel. I used --enable-uxa instead of --enable-sna and it seems to work without this problem so far (been using it for only a few hours now). working: --enable-dri --enable-xvmc --disable-dga --disable-xaa --enable-udev --enable-uxa --disable-sna not working: --enable-dri --enable-xvmc --disable-dga --disable-xaa --enable-udev --disable-uxa --enable-sna
This did not happen for a while now. I'm currently running: Kernel: 3.16.2 Mesa: 10.2.7 xorg-server: 1.16.0 xf86-video-intel: 2.99.916
