--- Comment #5 from Alexandre Demers alexandre.f.demers@gmail.com 2012-08-07 01:21:27 UTC --- Tested running one piglit test at a time (thanks Michel) and it always locks on "texturing/depthstencil-render-miplevels 146 s=z24_s8_d=z32f_s8". It locks hard, resets, stays locked and usually restarts the computer.
