<pre>On the current mainline kernel, 3.19-rc4 as of 2015-01-11, I still get the gpu
hang through a few different ways:
[ 48.398180] [drm] stuck on render ring
[ 48.398984] [drm] GPU HANG: ecode 7:0:0x85dffffd, in Xorg.bin [354], reason:
Ring hung, action: reset
[ 48.398988] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 48.398989] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 48.398991] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 48.398993] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 48.398994] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 48.399059] [drm:intel_pipe_set_base [i915]] *ERROR* pin & fence failed
[ 48.404834] drm/i915: Resetting chip after gpu hang
[ 54.389676] [drm] stuck on render ring
[ 54.390431] [drm] GPU HANG: ecode 7:0:0x85dffffd, in Xorg.bin [354], reason:
Ring hung, action: reset
[ 54.390500] [drm:intel_pipe_set_base [i915]] *ERROR* pin & fence failed
[ 54.390513] [drm:i915_set_reset_status [i915]] *ERROR* gpu hanging too fast,
banning!
[ 54.396341] drm/i915: Resetting chip after gpu hang
I can trigger this error only once after rebooting and then running the
command:
xrandr --output HDMI1 --off --output VIRTUAL1 --off --output eDP1 --mode
1920x1080 --pos 0x0 --rotate normal --output VGA1 --off
Starting chromium without the flag --disable-gpu always produces the error:
[ 561.799135] [drm] stuck on render ring
[ 561.799939] [drm] GPU HANG: ecode 7:0:0x85dfbff8, in chromium [917], reason:
Ring hung, action: reset
[ 561.805793] drm/i915: Resetting chip after gpu hang</pre>
