[Problem]
GPU lockup on Sandybridge.  User had 10+ applications open, but don't know if that was involved in the cause.  User doesn't think any of the apps were 3D; perhaps the crash was triggered by compiz itself?

I can confirm this is 3D related, happens to me whenever I am playing Civ4 under Wine.

Comment 6 Kenneth Graunke 2011-10-21 11:28:54 UTC

Here's a proposed fix:
http://lists.freedesktop.org/archives/mesa-dev/2011-October/013518.html
I developed it against master, but it ought to apply to 7.11 as well.

Comment 7 Kenneth Graunke 2011-10-24 14:26:12 UTC

Fix is now in Mesa master.

commit 3cc0a7be23ab603ed40d602595f673a44e079885

    i965: Apply post-sync non-zero workaround to homebrew workaround.
    
    In commit 3e5d3626, Eric added a homebrew workaround to fix GPU hangs in
    the Mesa "engine" demo and oglc's api-texcoord test.
    
    Unfortunately, his PIPE_CONTROL contains a Depth Stall, which
    necessitates the post-sync non-zero workaround,
    
    Fixes GPU hangs in Civilization 4, PlaneShift, and 3DMMES.
    Hopefully Heroes of Newerth as well, though I haven't tested that.
    
    NOTE: This is candidate for the 7.11 branch.

Fix is now in 7.11 branch as commit 439628318bfd4596d0d8129a0792d2c3ea849bb7; it will appear in the upcoming 7.11.1 release.
