mesa, libdrm, ddx from git

With kernel <3.8 all looks fine.
Comment 1 Michel Dänzer 2013-02-04 10:23:16 UTC 
Could be related to bug 60236. If that's not it, can you bisect which kernel change introduced the problem?
Comment 2 Iaroslav Andrusyak 2013-02-04 12:23:45 UTC 
I know that the problem appeared after upgrading to 3.8-rc1-drm-next, and continues to exist in the 3.8-rc5-vanilla.
async dma is a likely cause.

Please test with this mesa patch (either against mesa 9.1git or mesa master git).

If it fix the issue then please test making sure you a have kernel with this kernel patch :

Comment 4 Jerome Glisse 2013-02-13 16:42:55 UTC 
Test kernel without the mesa patch.
