crash dump

I have a lenovo w520, somethings happens a gpu freeze for some second

[22718.418826] [drm] stuck on render ring
[22718.418829] [drm] GPU crash dump saved to /sys/class/drm/card1/error
[22718.418830] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[22718.418831] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[22718.418832] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[22718.418832] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

I use kde, and patches mesa according to https://bugs.freedesktop.org/show_bug.cgi?id=70706

I had freezes also using xorg 1.14 and without those patches

It happens almost always when switching task (with kwin composer effect)
Comment 1 Chris Wilson 2014-02-27 00:41:39 UTC 
This is likely fixed in recent stable releases of mesa. Please try updating your libGL and report what version you have (paste the output of glxinfo).
Comment 2 Gianluigi Tiesi 2014-02-27 02:52:29 UTC 
oh I forgot to say mesa version:
9.2.2-1

it's not easy to use 10, experimental has 10.0.2-1
but I suppose I'll screw all the system without really having a good way to reproduce the problem

You say it's fixed, I even suspect an hardware problem on my laptop (it happened also on window), so I think you can safely closed the bug for now
Comment 3 Kenneth Graunke 2014-02-27 18:12:14 UTC 
Mesa 9.2.3 has a number of critical fixes for GPU hangs on Sandybridge.  You'll need to upgrade to at least that.  10.x has a few additional fixes.

If you still have problems with those releases, feel free to reopen.
