X freezes when I start glxgears. I can't move the mouse nor reset with ctrl-alt-canc. I'm running master git mesa (last commit 150d4968e31e4600f9479c53f83d810b92b59cf7, st/xorg: Initialize pipe in the renderer), git radeon drivers, libdrm v2.4.15 and kernel v2.6.31.

This should help detecting possible memory leaks with dma buffers and prevent possible visual corruption if data would be overwriten too early. Reverting this commit fixes the problem.
