is this thing supported, or should I buy a real graphics card?

didn't notice a WARN_ON logged:
WARN_ON(dev_priv->fence_regs[obj->fence_reg].pin_count);

now I tried mplayer with kernel-3a69ddd6f872180b6f61fda87152b37202118fbc and 
mesa-b328949a37.

[  456.495796] [drm:i915_gem_object_bind_to_gtt] *ERROR* Attempting to bind a purgeable object

(this is a new error not seen earlier)
It is not wedged, fortunately.  mplayer exited when it got that error.

I've tried mplayer -vo gl on any number of videos, across several different versions of software, and I've never had any GPU hangs.  It all seems to be working fine.  This is also on Sandybridge GT2.

I almost wonder if the reporter has a hardware problem, considering that he also gets GPU hangs playing simple games like Neverball.

Does
Option "SwapbuffersWait" "false"
in Section "Device" of xorg.conf make any difference?

I haven't had hangs since July.
My hardware is still the same, so it was a software problem.

Must have been fixed at some point then.  Closing.
