<pre>I'm trying to persuade a Haswell G1820TE to run stable for long periods of
time, but I keep getting GPU hangs.
[ 414.334623] [drm] stuck on render ring
[ 414.336340] [drm] GPU HANG: ecode 0:0x87d3bffa, in screen_manager [878],
reason: Ring hung, action: reset
[ 414.336351] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 414.336356] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 414.336360] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 414.336365] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 414.336370] [drm] GPU crash dump saved to /sys/class/drm/card0/error
I've tried using i915.use_mmio_flip=1, but still get the hang.
What am I doing wrong?
Device is Intel(R) Celeron(R) CPU G1820TE @ 2.20GHz.
Packages:
* kernel-3.17.0-0.rc4.git0.1.fc22.x86_64
* libdrm-2.4.54-1.fc20.x86_64
* mesa-dri-drivers-10.1.5-1.20140607.fc20.x86_64
* xorg-x11-drv-intel-2.21.15-7.fc20.x86_64
* xorg-x11-server-Xorg-1.14.4-5.fc20.x86_64
I can add more information if needed - I'll attach a gzip compressed version of
the error state from when I has use_mmio_flip=1</pre>
